Proper storage of lithium-ion batteries ensures long-term safety and performance. Store batteries in a cool, dry place, away from direct sunlight and heat sources. Avoid storing batteries in vehicles or areas with temperature fluctuations.

• Store batteries at a partial charge, ideally around 50%. This reduces stress and prevents capacity loss.

• Keep batteries away from metal objects that could cause short circuits.

• Place spent or unused battery packs outside or in a fire-safe container to avoid hazards from delayed cell propagation.

Note: Never store swollen or damaged batteries. Dispose of them following proper procedures.

1.4 Disposal Steps

Disposing of lithium-ion batteries safely protects your workplace and the environment. Never throw batteries in regular trash or incinerate them.

• Use certified recycling programs or hazardous waste facilities for disposal.

• Place spent batteries in non-conductive containers, such as plastic bags or original packaging.

• If a battery appears swollen or damaged, isolate it from other batteries and handle it with gloves.

Part 2: Don’ts for Preventing Fires

2.1 Charging Mistakes

Charging lithium-ion batteries incorrectly can lead to severe fire hazards. You must never overcharge the lithium-ion batteries. Overcharging causes internal pressure to build up, which increases the risk of thermal runaway. This process can make the battery catch on fire or even explode. You should avoid using damaged chargers or cables. Faulty charging equipment can trigger short circuits, leading to battery fires and explosions.

Never leave batteries unattended during charging. If a battery becomes swollen, hot, or emits a strange odor, remove the battery from the charger immediately. Swollen batteries signal internal damage and present a high risk of fire or explosion. Charging on flammable surfaces, such as paper or fabric, increases the danger. Always use a designated, non-flammable charging area.

⚠️ Alert: Never use extension cords or daisy-chain power strips for charging lithium-ion batteries. These setups can overheat and cause fires.

You should also avoid charging batteries in extreme temperatures. Charging below freezing or above 45°C can cause lithium plating or accelerate thermal runaway. Both conditions increase the risk of battery fires and explosions.

2.2 Storage Errors

Improper storage of lithium-ion batteries creates serious fire risks. Do not store batteries in direct sunlight or near heat sources. High temperatures can cause batteries to swell, leak, or enter thermal runaway. You should never store batteries in vehicles or unventilated spaces, where temperatures can fluctuate rapidly.

Avoid placing batteries near metal objects. Metal can bridge the terminals and cause a short circuit, leading to fire or explosion. Never store swollen batteries with healthy ones. Swollen batteries can rupture and ignite, putting your entire inventory at risk.

Tip: Use fire protection cabinets or fire-resistant containers for bulk battery storage. This step helps in preventing fires from spreading in case of an incident.

Do not stack heavy items on top of battery packs. Excessive pressure can damage the cells, causing internal shorts and increasing the risk of thermal runaway.

2.3 Handling Damage

You must never ignore physical damage to lithium-ion batteries. Dropping, crushing, or puncturing a battery can compromise its internal structure. Damaged batteries often become swollen, leak, or emit gas. These signs indicate a high risk of fire or explosion.

Do not attempt to repair or modify battery packs yourself. Unauthorized repairs can bypass safety features and increase the chance of thermal runaway. If you notice a swollen battery, isolate it from other batteries and equipment. Remove the battery from service and follow your company’s hazardous materials protocol.

⚠️ Note: Never use a battery that has been exposed to water or chemicals. Contaminants can cause internal corrosion, leading to battery fires or explosions.

You should always use personal protective equipment when handling damaged or swollen batteries. Gloves and safety glasses protect you from chemical burns and flying debris in case of an explosion.

2.4 Disposal Risks

Disposing of lithium-ion batteries improperly poses significant fire and explosion hazards. Never throw batteries in regular trash or incinerate them. Damaged or swollen batteries can ignite during transport or landfill processing.

• Nail penetration tests on lithium-ion cells from disposable e-cigarettes showed temperatures reaching up to 495°C, indicating significant fire and explosion hazards during disposal.

• These cells exhibited substantial gas expulsion upon damage, further highlighting safety risks.

• Cycling performance data revealed that so-called disposable cells can undergo hundreds of charge/discharge cycles (up to 474-700 cycles), implying a large volume of potentially reusable batteries being discarded.

• The disposal of these rechargeable cells represents a considerable waste of critical resources like lithium, raising environmental and safety concerns.

• The study emphasizes the urgent need for regulatory intervention to address these disposal risks.
