What are the types of batteries?

Batteries have become the main energy storage products in modern society. Currently, mainstream electric vehicles and various electronic products all require batteries. Batteries basically convert chemical energy into electrical energy through redox reactions, and different types of batteries are applied in different application scopes. The following is a relatively comprehensive overview of batteries, classified by their chemical properties, rechargeability and usage.
Primary batteries are designed for single-use; once their chemical energy is depleted, they cannot be recharged. They are commonly used in low-power, infrequently used devices due to their convenience and long shelf life
 
•Alkaline Batteries
 
Alkaline Batteries mainly consist of sodium hydroxide and manganese dioxide as their chemical components. They have a moderate energy density and a stable voltage output, typically around 1.5V. Their shelf life ranges from 5 to 10 years. They are mainly used in products such as flashlights, toys, and remote controls. They are inexpensive, widely used, and not prone to leakage.
 
•Carbon-Zinc Batteries
 
Their main chemical components include zinc, carbon, and manganese dioxide. They have a lower energy density than alkaline batteries, with a typical voltage of 1.5V and a shelf life of 2-3 years. They are mainly used in low-power-consuming products such as clocks, calculators, and smoke detectors. Their disadvantage is that they are prone to leakage at high temperatures, and most of them in the market have been gradually replaced by alkaline batteries.
 
•Lithium Primary Batteries
 
Their main chemical components include lithium, manganese dioxide, and iron disulfide. They feature high energy density, an operating temperature range of -40°C to 60°C, and a shelf life of 10-15 years. The voltage ranges from 1.5V to 3V. They are mainly applied to cameras, medical devices, watches, and military products. Characterized by light weight and reliable performance across temperatures, they are suitable for long-term, low-power consumption scenarios.
 
Secondary batteries, as the name suggests, can be recharged multiple times by reversing chemical reactions, making them highly suitable for high-power, repeatedly used devices.
 
• Lithium-Ion (Li-Ion) Batteries
 
Lithium ions mainly move between a graphite anode and a metal oxide cathode in an organic electrolyte. They boast high energy density and a low self-discharge rate (2-3% per month), with a voltage of 3.6V-3.7V per cell.
 
Lithium Cobalt Oxide (LCO): Primarily used in smartphones, laptops, electric vehicles, etc. Due to its relatively low thermal stability, it is mainly applied in consumer electronics.
 
Lithium Iron Phosphate (LFP): Safer, with more cycles and a longer lifespan, it is used in electric vehicles and energy storage systems.
 
Lithium Nickel Manganese Cobalt Oxide (NMC): Balancing energy density and safety, it is commonly used in electric vehicles and power tools.
 
• Lithium Polymer (Li-Po) Batteries
 
Similar to lithium-ion batteries, they use a polymer electrolyte (solid or gel) instead of a liquid one, thus eliminating the need for a rigid casing. These batteries feature a flexible form factor, light weight, and customizable shapes. Their voltage ranges from 3.7V to 4.2V. They are mainly used in drones, wearable devices, tablets, and the like.
 
• Nickel-Cadmium (Ni-Cd) Batteries
 
They mainly consist of a cadmium anode, a nickel oxide hydroxide cathode, and potassium hydroxide as the electrolyte. Featuring low energy density, high durability in extreme temperatures, each cell has a voltage of 1.2V. They are used in power tools, emergency lighting, and medical equipment. Though widely applied historically, their usage is gradually declining. This is primarily because they contain toxic cadmium, which is restricted by regulations such as RoHS, and they also suffer from the “memory effect”.
 
• Nickel-Metal Hydride (Ni-MH) Batteries
These batteries mainly consist of a hydrogen-absorbing alloy anode, a nickel oxide hydroxide cathode, and an alkaline electrolyte. They have a higher energy density than nickel-cadmium batteries, contain no toxic metals, and each cell has a voltage of 1.2V. They are mainly used in hybrid electric vehicles, digital cameras, and rechargeable AA/AAA batteries. They have better environmental performance than nickel-cadmium batteries and exhibit less memory effect, but their self-discharge rate is relatively high, at 10-15% per month.
 
• Lead-Acid Batteries
 
These batteries mainly consist of a lead dioxide positive electrode, a lead negative electrode, and a sulfuric acid electrolyte. They feature low energy density, high output power, and a single cell voltage of 2V, with 6V or 12V systems being common.
 
Types include:
 
Flooded Lead-Acid Batteries: A traditional type that requires long-term maintenance and electrolyte replenishment. They are used in cars, motorcycles, and backup power supplies.
 
Valve-Regulated Lead-Acid (VRLA) Batteries: Sealed and maintenance-free, they are used in uninterruptible power supplies (UPS) or solar energy systems.
Both types of batteries have the advantages of very low cost and reliable performance. Their disadvantages are heavy weight and environmental pollution issues.
 
As demand for high-performance, sustainable energy storage grows, several innovative battery types are under development:
 
• Solid-State Batteries
 
Solid-state batteries replace liquid electrolytes with solid materials, thereby improving energy density and battery safety. They may be applied to electric vehicles, smartphones, or power grids in the future. Compared with lithium-ion batteries, solid-state batteries have lower fire risk, faster charging speed, and more cycles.
 
• Sodium-Ion Batteries
 
These batteries mainly utilize sodium resources, which are abundant in output and low in cost, replacing lithium ions with sodium ions. They operate on a similar principle to lithium-ion batteries but have lower energy density. They are mainly applied in grid energy storage, low-cost electric vehicles, or energy storage needs in regions with limited lithium resources
 
These are batteries that need to be used in specific products. Most of these batteries require customized development, featuring characteristics such as small usage volume and high unit price.
 
• Button Cells
 
These are generally small, coin-shaped batteries used in compact products. Primary (disposable) button cells are used in items such as watches, hearing aids, and remote controls. Secondary (rechargeable) button cells are mainly used in small wearable devices.
 
• Reserve Batteries
 
These batteries are activated only when needed, typically by adding water or electrolyte. They offer an ultra-long shelf life, usually up to ten years. They are used in military equipment, emergency beacons, and space missions.
 
 
The above has introduced the diversity of batteries, which also play a crucial role in modern life. From household power supply to energy storage in industrial production, batteries provide more convenient lives. However, the diversity of batteries also brings more challenges to shipping lithium batteries.

Can you ship batteries safely?

What we have been mentioning are the applications in smartphones, laptops, electric vehicles, and energy storage systems—batteries provide the main energy for all these. As the usage rate of batteries continues to grow, the demand for shipping will also increase accordingly. This is especially true for global transportation, where lithium batteries produced in China are shipped to all parts of the world. However, batteries are classified as dangerous goods under many regulations, which gives rise to the question: “Can you ship batteries safely?” My answer is definitely yes. But during transportation, it is necessary to strictly comply with shipping guidelines, packaging requirements, and regulatory standards. The following is a detailed guide on battery shipping.
 
When it comes to batteries, especially lithium-ion batteries and lithium metal batteries, there are potential risks involved in their transportation. If batteries are damaged, mishandled, or exposed to conditions like extreme heat from direct sunlight, these situations may cause the batteries to short-circuit or overheat, leading to fires. Such incidents can result in threats to personal safety and loss of property. Therefore, in accordance with international regulations, lithium-ion batteries are classified as “Class 9 Miscellaneous Dangerous Goods”. Stringent safety measures must be implemented to prevent fires or explosions when shipping lithium batteries.
 
 
Safe battery shipping begins with compliance with global and national regulations. These rules vary by battery type, quantity, and mode of transport (air, sea, road, or rail):
 
  • United Nations (UN): The UN establishes global standards, and batteries are categorized under codes such as UN3090 and UN3480. They are required to undergo tests like UN38.3, which evaluate the battery’s performance in terms of temperature resistance, vibration resistance, impact resistance, and overall tolerance.
  • Air Transport: Governed by the International Air Transport Association (IATA) Dangerous Goods Regulations (DGR) and the International Civil Aviation Organization (ICAO) Technical Instructions. These mandate UN-approved packaging, hazard labels (e.g., Class 9), and a Shipper’s Declaration for Dangerous Goods. Restrictions include limits on watt-hour ratings and quantities per shipment.
  • Sea Transport: Regulated by the International Maritime Organization (IMO) International Maritime Dangerous Goods (IMDG) Code, which covers packaging, stowage, and documentation to minimize risks at sea.
  • National Rules: Countries like the U.S. (Department of Transportation), EU (ADR for road transport), and China (Civil Aviation Administration) enforce additional requirements, from labeling to training for handlers.
 
Proper packaging is critical to prevent damage and short-circuits:
 
  • General Guidelines: Batteries must be shielded from physical impact, moisture, and extreme temperatures. Loose batteries should be insulated (e.g., with tape over terminals) to avoid contact with metal objects.
  • UN-Approved Packaging: High-risk shipments (e.g., large lithium-ion batteries) require packaging tested and certified to UN standards, with sturdy outer casings and inner padding to absorb shocks.
  • Batteries in Equipment: When shipped with devices (e.g., a laptop with its battery), the equipment must be powered off, and batteries secured to prevent movement. This reduces the risk of accidental activation.
 
Clear communication ensures handlers understand risks and procedures:
 
  • Labels and Marks: Packages must display hazard labels (e.g., the Class 9 symbol), UN numbers, and handling instructions (e.g., “Keep Away from Heat”). Air shipments may require “Cargo Aircraft Only” labels for high-capacity batteries.
  • Documentation: Essential documents include a Shipper’s Declaration for Dangerous Goods (detailing battery type, quantity, and UN test compliance), UN38.3 test reports, and certificates of conformance. For commercial shipments, air waybills or bills of lading must clearly identify the cargo as dangerous goods.

• Lithium-Ion Batteries: Avoid shipping damaged or recalled units. Ensure they are fully charged to no more than 30% for air transport (per IATA guidelines) to reduce fire risk.

•Lead-Acid Batteries: Prevent leakage by using spill-proof packaging. Flooded lead-acid batteries require vented containers to release hydrogen gas safely.
 
•Primary vs. Secondary Batteries: Disposable batteries (e.g., alkaline) have fewer restrictions but still need protection, while rechargeable batteries (e.g., Ni-MH) demand careful handling to avoid over-discharge during transit.
 
 
Handlers, shippers, and logistics staff must be trained to recognize battery types, understand risks, and respond to incidents (e.g., using fire extinguishers rated for electrical fires). Many regulations mandate certified training programs to ensure compliance.
 
 
Although shipping batteries inherently involves risks, as long as we comply with relevant regulations and use professional packaging, the safety of transportation can be ensured. For this, you need to find a professional freight forwarder in China. Batteryshipment.com is a professional lithium battery shipping freight forwarder based in Shenzhen.

Batteries are ubiquitous in modern life, powering everything from small electronics to large industrial equipment. However, their chemical composition and energy storage capabilities make them subject to strict transportation regulations, as improper handling can pose risks like short circuits, fires, or chemical leaks. Among these, shipping lithium batteries demands particular attention due to their higher energy density and associated safety hazards. Shipping different types of batteries requires tailored approaches to ensure compliance, safety, and efficiency. Below is a guide to navigating the complexities of shipping common battery types, with a detailed focus on shipping lithium batteries.
 
 
Shipping lithium batteries requires strict adherence to regulations, as lithium-based batteries are among the most widely used and regulated, due to their high energy density and fire risk.
 
Classification:
  • Lithium-ion batteries (rechargeable) are classified as UN3480 (standalone) or UN3481 (installed in equipment).
  • Lithium metal batteries (non-rechargeable, containing metallic lithium) are labeled UN3090 (standalone) or UN3091 (installed in equipment).
Key Requirements:
  • Must pass UN38.3 testing, which evaluates performance under extreme temperatures, vibration, shock, and short circuits.
  • Air transport (per IATA DGR) limits lithium-ion battery charge to 30%–50% to reduce fire risk; bulk shipments often require “cargo aircraft only” designation.
  • Packaging must be UN-approved, with terminals insulated (e.g., taped) to prevent short circuits. Labels must display the Class 9 hazard symbol, UN number, and handling instructions.
 
Similar to lithium-ion batteries but using polymer electrolytes, Li-Po batteries are flexible and common in drones, wearables, and smartphones.
 
Regulations:
 
1.Classified under the same UN numbers as lithium-ion batteries (UN3480/UN3481) due to similar risks.
2.Require careful packaging to avoid punctures, as their flexible casings are more prone to damage than rigid lithium-ion batteries.
3.Air and sea transport rules mirror those for lithium-ion batteries, with strict limits on quantity per shipment.
 
 
These rechargeable batteries are less energy-dense than lithium-based options but still require attention to safety.
 
• Ni-MH Batteries:
 
1.Generally classified as non-dangerous for small quantities, but large shipments may fall under Class 8 (corrosive) due to alkaline electrolytes.
2.Packaging should prevent leakage; no special labeling is needed for consumer-sized units, but industrial quantities require compliance with IMDG (sea) or ADR (road) rules.
 
• Ni-Cd Batteries:
 
1.Contain toxic cadmium, classified as UN2794 (standalone) or UN2800 (installed in equipment) under dangerous goods regulations.
2.Strictly regulated by RoHS and other environmental laws; shipping requires proof of proper disposal plans in some regions.
3.Must be packaged to prevent short circuits and labeled with “Toxic” or “Environmentally Hazardous” warnings where applicable.
 
 
Widely used in vehicles, UPS systems, and backup power, lead-acid batteries are heavy and contain corrosive sulfuric acid.
 
• Classification:
 
1.Classified as UN2794 (flooded lead-acid) or UN2800 (sealed lead-acid), falling under Class 8 (corrosive substances).
 
• Shipping Rules:
 
1.Flooded (wet) lead-acid batteries require vented packaging to release hydrogen gas and prevent pressure buildup.
2.Sealed (valve-regulated) lead-acid (VRLA) batteries are less hazardous but still need leak-proof packaging.
3.All shipments must display corrosive hazard labels and include material safety data sheets (MSDS) detailing spill response procedures.
 
 
Common in household items like remote controls and flashlights, alkaline batteries are low-risk but not entirely unregulated.
 
• Regulations:
 
1.Generally exempt from dangerous goods classification in small quantities, as they are non-rechargeable and have low energy density.
2.Large commercial shipments may require compliance with basic packaging standards to prevent short circuits (e.g., separating batteries to avoid contact with metal).
3.Some countries restrict disposal of alkaline batteries, but shipping rules are minimal compared to lithium or lead-acid variants.
 
 
Button cells, reserve batteries, and sodium-ion batteries have unique shipping needs:
 
  • Button Cells: Small, coin-shaped batteries (e.g., in watches) are often shipped in bulk. They require insulation to prevent contact and may be classified under lithium or alkaline categories depending on chemistry.
  • Reserve Batteries: Activated by water or electrolyte, these are classified as UN3256 and require labels indicating they are “Not Restricted When Unactivated.”
  • Sodium-Ion Batteries: Emerging as a low-cost alternative to lithium, they are regulated similarly to lithium-ion batteries but with fewer global standards—check destination-specific rules.

 

• Know the Destination: Regulations vary by country (e.g., EU REACH, U.S. DOT, China’s Civil Aviation Administration). Verify import restrictions and required certifications.

• Use Certified Packaging: Invest in UN-approved containers tested for the specific battery type and quantity.

• Document Thoroughly: Include a Shipper’s Declaration for Dangerous Goods, UN38.3 reports (for lithium batteries), and MSDS where required.
 
•Train Personnel: Ensure handlers understand battery-specific risks, emergency protocols (e.g., using appropriate fire extinguishers), and labeling requirements.
 
Shipping different types of batteries demands careful attention to their unique chemistries, regulations, and risks. Whether transporting lithium-ion batteries for electric vehicles or alkaline batteries for consumer goods, compliance with global and local standards is non-negotiable. By understanding classification rules, investing in proper packaging, and partnering with experienced logistics providers, businesses can ensure safe, efficient, and legally sound battery shipments worldwide.

Battery shipping regulations

Batteries have become a crucial pillar of modern technology. Our mobile phones, the currently popular electric vehicles, renewable energy sources, and various devices all rely on batteries for energy supply. The transportation of lithium batteries also plays a pivotal role in commercial activities, driven by the rapid growth of global trade. According to industry reports, the global lithium battery market has experienced exponential growth, with trade volumes increasing by more than 20% annually in recent years. This growth is mainly attributed to the booming development of electric vehicles, which are expected to account for 35% of global car sales by 2030, as well as the popularization of portable electronic devices and energy storage systems. Such a significant increase in trade volume makes the safe and compliant transportation of lithium batteries a necessity and also a key factor in maintaining the integrity of the global supply chain.
 
Batteries are classified as dangerous goods under most global frameworks due to their energy-dense nature and potential for thermal runaway (a self-sustaining chain reaction of overheating). For example, lithium-ion batteries, widely used in consumer electronics and EVs, can short-circuit or ignite if damaged, exposed to extreme temperatures, or improperly packaged. Similarly, lead-acid batteries contain corrosive sulfuric acid, while nickel-cadmium (Ni-Cd) batteries include toxic cadmium. These hazards necessitate strict regulations to mitigate risks during air, sea, road, or rail transport.
 
 
A handful of key organizations set the foundation for global battery shipping rules, which are then adopted or adapted by nations worldwide:
United Nations (UN) Recommendations
 
The UN’s Recommendations on the Transport of Dangerous Goods (also known as the “Orange Book”) is the cornerstone of international regulation. It:
 
  • Assigns UN numbers to identify battery types (e.g., UN3480 for lithium-ion batteries, UN2794 for lead-acid batteries).
  • Mandates UN38.3 testing for lithium-based batteries, a series of rigorous evaluations (altitude, temperature, vibration, shock, and short-circuit tests) to ensure they can withstand transit conditions.
  • Establishes guidelines for packaging, labeling, and documentation, which are adopted by most countries and specialized transport bodies.
 
Air Transport: IATA and ICAO
 
Airlines follow strict rules due to the high risks of in-flight fires:
 
  • International Air Transport Association (IATA): Its Dangerous Goods Regulations (DGR) outlines packaging, labeling, and quantity limits. For example, lithium-ion batteries shipped as cargo are often restricted to “cargo-only aircraft,” and their state of charge (SOC) is capped at 30–50% to reduce fire risk.
  • International Civil Aviation Organization (ICAO): A UN agency that publishes Technical Instructions for the Safe Transport of Dangerous Goods by Air, which aligns with IATA standards but is legally binding for all ICAO member states (193 countries).
 
Sea Transport: IMO’s IMDG Code
 
The International Maritime Organization (IMO) governs maritime transport via the International Maritime Dangerous Goods (IMDG) Code. It specifies:
 
  • Stowage requirements (e.g., keeping batteries away from flammable materials).
  • Packaging standards to prevent leakage or damage in rough seas.
  • Documentation, including a dangerous goods declaration and emergency response information.
 
Road and Rail Transport
 
Land transport regulations vary by region but often align with UN standards:
 
  • ADR (European Agreement Concerning the International Carriage of Dangerous Goods by Road): Governs road transport in Europe, requiring vehicles to carry safety equipment and drivers to hold specialized licenses.
  • RID (Regulations Concerning the International Carriage of Dangerous Goods by Rail): Applies to rail transport across Europe and beyond, with rules for battery stowage and handling.
  • National Rules: Countries like the U.S. (via the Department of Transportation, DOT) and China (via the Ministry of Transport) enforce their own variations, including labeling and training requirements for handlers.
 
While specifics vary, core regulations for battery shipping include:
 
  1. Classification and Identification
  • Batteries must be correctly classified by type (e.g., lithium metal vs. lithium-ion) and assigned the appropriate UN number.
  • Shipping documents must clearly state the battery type, UN number, and quantity to ensure handlers understand risks.
  1. Packaging
  • UN-approved packaging: High-risk batteries (e.g., lithium-ion) require packaging tested to UN standards, with shock-absorbent materials and leak-proof barriers.
  • Insulation: Battery terminals must be insulated (e.g., with tape or caps) to prevent short circuits from contact with metal objects.
  • Equipment-integrated batteries: When shipped with devices (e.g., a laptop), the device must be powered off, and the battery secured to prevent movement.
  1. Labeling and Marking
  • Packages must display hazard labels (e.g., the Class 9 “miscellaneous dangerous goods” symbol for lithium batteries).
  • UN numbers, handling instructions (e.g., “Keep Away from Heat”), and orientation arrows (to prevent incorrect stacking) are mandatory.
  1. Documentation
  • A Shipper’s Declaration for Dangerous Goods is required for most air and sea shipments, certifying compliance with regulations.
  • UN38.3 test reports, material safety data sheets (MSDS), and proof of packaging compliance may also be required.
 
While global frameworks exist, regional differences can complicate shipping:
 
  • The European Union (EU) enforces strict environmental rules (e.g., RoHS) that restrict cadmium in batteries, affecting Ni-Cd shipments.
  • The United States requires compliance with DOT regulations, including training for all personnel involved in battery transport.
  • China has specific rules for air transport of lithium batteries, including pre-approval for certain shipments and strict documentation checks.
Staying updated on these variations is critical to avoid delays, fines, or cargo seizure.

For lithium-based batteries, obtain a valid UN38.3 test report, which certifies they can withstand extreme conditions like temperature fluctuations, vibration, and shocks during transit.
Invest in packaging certified to UN standards, with shock-absorbent materials and insulation (e.g., tape over terminals) to prevent short circuits and physical damage.
For air transport, keep lithium-ion battery SOC below 30–50% (per IATA guidelines) to reduce fire risk. Check specific limits for your shipping mode.
Attach required labels, including the Class 9 hazard symbol, UN number, and orientation arrows. For air shipments, add “Cargo Aircraft Only” labels if applicable.
Include a Shipper’s Declaration for Dangerous Goods, UN38.3 test reports, and material safety data sheets (MSDS) to meet regulatory requirements and avoid delays.
Work with freight forwarders experienced in battery shipping, as they understand regional rules (e.g., IATA, IMDG Code) and can navigate complex compliance steps.
Ensure personnel know how to respond to incidents (e.g., using fire extinguishers for electrical fires) and recognize signs of battery damage (e.g., swelling, leakage).
Research import restrictions, certifications (e.g., EU CE, US UL), and local regulations to avoid customs hold-ups—requirements vary by country.
Avoid shipping damaged, swollen, or recalled batteries. Ensure all units are intact, with no exposed terminals or leaks, to minimize in-transit risks.
