Introduction:
With the rapid development of science and technology, lithium batteries have been widely used in consumer electronics, electric vehicles and energy storage due to their high energy density and environmental protection characteristics. However, there are also certain safety risks. Accidents caused by improper use of lithium batteries are common. This blog will analyze the safety risk factors of lithium batteries in detail and explore how to prevent and deal with related accidents to ensure safety when using lithium batteries.
Safety risks of lithium batteries
Thermal runaway: When the temperature inside the lithium battery is too high, it may cause a short circuit inside the battery or accelerate chemical reactions, which may lead to fire or explosion.
Battery damage: Impact, extrusion or corrosion of the lithium battery may cause damage to the internal structure, causing safety problems.
Overcharge/over discharge: Overcharging or over discharge will increase the internal pressure of the battery, which may cause the battery to rupture or burn.
Short circuit: Short circuit inside the lithium battery or in the connecting line may cause the lithium battery to overheat, burn or explode.
Battery aging: As the use time increases, the lithium battery performance gradually decreases, posing a safety hazard.
Preventive measures
1. Choose regular brands and channels
When purchasing lithium batteries, you should choose regular brands and channels to ensure that the battery quality meets relevant standards.
2. Reasonable use and charging
Use lithium batteries strictly in accordance with the product manual and operating specifications to avoid overcharging, discharging and abuse.
When charging, use the original charger or a certified third-party charger to avoid using mismatched or inferior chargers.
There should be someone on duty during the charging process to avoid long-term continuous charging. The power should be turned off in time after the battery is fully charged.
3. Safe storage and transportation
Store lithium batteries in a cool, dry and ventilated place, away from high temperature, fire and flammable items.
Avoid placing lithium batteries in direct sunlight or high temperature environments to prevent the internal chemical reaction of the battery from intensifying.
Anti-shock and anti-pressure measures should be taken during transportation to ensure battery safety.
4. Regular inspection and maintenance
Regularly check the appearance, power and use status of lithium batteries, and deal with problems in time.
Batteries that are not used for a long time should be protected individually to prevent short circuits, and the power should be checked regularly to avoid permanent damage to the battery.
5. Equipped with protection devices
Use a battery management system (BMS) with protection functions such as overcharge, over discharge, short circuit and high temperature to improve battery safety.
When using lithium batteries, corresponding protective devices such as temperature controllers, pressure sensors, etc. can be equipped to monitor the battery status and take safety measures in time.
6. Strengthen education and training and emergency response
Provide safety education and training for personnel using lithium batteries to improve their awareness of battery safety and emergency response capabilities.
Understand the emergency response methods for lithium battery safety accidents, equip fire extinguishing equipment and safety warning signs to ensure rapid response in emergency situations.
7. Track new technologies and developments
Pay attention to new technologies and development trends in the field of lithium batteries, and promptly understand and adopt safer and more advanced battery and management technologies.
