Procedures for Lithium Battery Storage and Safety Protection

Risk Overview

be in accordance with UN38.3 on Manual of Tests and Criteria for Recommendations on the Transport of Dangerous Goods.


studies. Avoid direct contact with the contents of the battery and prevent inhalation

Chemical leaks would cause damage. Battery mechanical or electrical damage would cause contact injuries. Avoid skin and eye contact with electrolyte liquid.

Inhalation, skin contact or eye contact may cause irritation when battery is broken. Irritating steam can injure skin, eyes and respiratory mucosa

Exposure symptoms: Short-term lithium batteries can cause electrothermal damage when contact the skin

First aid measures

Eye contact with electrolyte liquid: Rinse quickly with flowing clear water for more than 15 minutes, raise the upper and lower eyelids, then seek medical treatment quickly

Skin contact with interior materials of battery: Remove attached clothing and rinse with soap and plenty of water for 15 minutes immediately.

Inhalation of the battery interior materials: Move to vent immediately, provide oxygen if needed, get medical attention quickly.

Ingestion: Drink 2 cups of milk or water, do not induce vomiting under personnel unconscious, seek medical treatment immediately.

Fire Control Measures

Hazardous characteristics: Not classified as Flammable dangerous goods.

Explosion hazard: overheat could cause interior materials overflow, Combustion products: CO2, CO, Metal oxide of Lithium and other irritating and toxic gases.

Fire extinguishing method and agent: Can be extinguished with dry powder, sand, foam and CO2.

Fire precautions and measures: Firefighters should wear self-contained positive-pressure respirators and fire protective clothing to prevent skin and eye contact.

Emergency Response

Leakage Response: Leak refers to leakage of interior electrolyte liquid from the battery, with acrid smell usually. The electrolyte liquid is highly corrosive and will cause damage to the battery protection board components, bulging will occur if it’s polymer battery. Liquid leaked and bulged battery must be picked out and destroyed. If the battery is broken and electrolyte liquid leak out, evacuate person until the smoke cleared, clean the battery with cloth and put it in bag and steel bucket. Disposal person should wear suitable protective clothing. If the battery is hot, keep it away from the scene and cool the battery to dissipate steam, adequate ventilation and avoid eye contact with steam.

Heat Treatment: The battery would heat when it’s charging or discharging, usually under 60℃。It’s will reach over 100when the battery is in the state of internal or external short circuit, the battery must be isolated and placed in the sand, do not touch the battery directly , or you will be burned. Disposal it after the battery temperature drops to normal.

Combustion or Explosion Treatment: Personnel must stay far away in the event of fire or explosion. Burning battery will not produce an open flame, high temperature could ignite flammable or package nearby usually. Under the premise of good protection, use sand to directly cover a burning or exploding battery if single or a few batteries are burning or explosion. Use the Dry powder fire extinguisher if it is a large area of combustion, NEVER use water for fire control, as it will cause short circuit of the battery.

Rusty Treatment: The initial and slight rust will not affect the performance of the lithium battery and can be used normally for cylindrical shaped lithium batteries (this phenomenon does not exist in polymer lithium batteries). If the rust is severe (such as the cap part), it will affect the sealing performance of the battery and leak the liquid, which must be discarded.

Waste disposal: The battery should be completely discharged, and the used batteries should be handed over to the factory office. All waste must be disposed of in accordance with the United Nations, national and local regulations.

Handling Precautions: Operators should be trained to strictly follow procedures. Operators should wear protective clothing and safety gloves for general work, keep away from fire and heat sources, and avoid direct sunlight. No smoking in the workplace. Workplaces should have ventilation systems and equipment. Avoid disassembling batteries and mistaken positive and negative poles. Battery should be firmly packed in the inner packaging to effectively prevent short circuits and prevent movement that can cause short circuits, and should be stored separately from strong oxidants and corrosives. In case of material leakage in the battery, avoid direct contact with eyes and skin and inhalation

Storage Precautions: Store in a cool, ventilated warehouse, away from fire and heat sources, and avoid direct sunlight, separately from strong oxidants and corrosives. The storage area should equipped with the corresponding variety and quantity of fire control equipment, leakage emergency treatment equipment and suitable containment materials.

Handling and Storage

Do not use batteries that are damaged or swollen.

Do not exceed the maximum discharge current specified in the battery specifications during use.

Do not disassemble the battery under any circumstances. Do not disassemble the battery, damage or incinerate, and do not damage the electrolyte liquid. Need to be stored in a sealed container.

Do not use metal objects such as wires to short-circuit the positive and negative terminals of the battery. Do not short circuit, overcharge, force discharge or throw into fire.

Welding of batteries is prohibited.

Do not squeeze or puncture the battery.

Do not put batteries in liquid.

Do not store rechargeable batteries with metal objects, to prevent metal objects from touching the positive and negative terminals of the battery, which could cause short circuits, damaging and even cause danger.

Do not knock, acupuncture, step on, modify, or expose the battery. Do not place the battery in a microwave or high voltage environment.

Operating and Storage: Mechanical or electrical damage to the battery is prohibited. Store in a dry, cool, ventilated environment, away from heat sources, and avoid prolonged sunlight. The battery can cause fire or explosion when disassembled, squeezed, exposed to fire or high temperature, short circuit or incorrect operation is prohibited

Short-term Storage: Store the battery in a dry, non-corrosive gas, and the temperature and humidity are between -20 ~ 35 65 ± 20% Storage in steel cabinet when the lithium battery is charged and not used / assembled for a short period of time (within 6 months).

Long-term Storage: Keep the battery 50%-70% charged and store in a dry and cool environment If the lithium battery is not used for a long time (more than 6 months). And charge it every 3 months to avoid the battery being too low due to self-discharge under long storage time, which may result in irreversible capacity loss.

Requirements for Storage: The warehouse should control the temperature and humidity to prevent the battery from being exposed to high temperature and humidity for a long time. The warehouse should have automatic fire extinguishing system, emergency sprinkler system, dry powder fire extinguisher and fire sands. Batteries should not be placed in the same place as flammable materials (such as packaging materials cartons, cartons, etc.), they should be placed in special storage steel cabinets. Stack the battery according to the instructions on the battery packaging and stacking requirements, do not exceed the limit.

Exposure Control / Personal Protection

Engineering controls: Ventilation systems and equipment, safety showers and eyewash equipment are required.

Respiratory protection: If batteries leak, adequate ventilation is required.

Hand protection: Wear safety gloves.

Personal protection: Wear general work protective clothing.

Other protection: smoking and eating are strictly prohibited at the work site.

If the battery leaks, personnel need to wear respirator, protective gloves, work clothes and chemical protective glasses.

Ecological Protection

Environmental impact: Proper use and disposal of batteries will not harm the environment.

Keep away from water, rain and snow when disposing of waste.


If the lithium battery is not fully discharged or is only partially discharged, the battery is considered a hazardous waste with a certain hazard because part of the unexhausted electricity is present in the battery. Disposal must be done through an approved scheme. Disposal of waste batteries should comply with the requirements of the relevant laws, regulations, policies and standards such as the “Law of the People’s Republic of China on the Prevention and Control of Environmental Pollution by Solid Wastes” and “Technical Policies for the Prevention and Control of Pollution from Waste Batteries”.
