Lithium battery as a battery with high performance and high energy density, it is widely used in various electronic products. However, due to its special chemical and structural characteristics, lithium batteries have some common potential safety hazards. Once problems occur, serious consequences such as fire and explosion may occur. This article will discuss the common potential safety hazards of lithium batteries and propose corresponding preventive measures.

1. Overcharge and overdischarge:
   overcharge and overdischarge are one of the most common security risks of lithium batteries. Overcharging will cause gas inside the battery, increase pressure and trigger explosion; While overcharging will cause electrolyte damage of the battery, leading to battery performance degradation and even fire. Preventive measures include using appropriate charging and discharging equipment, setting protection circuit, avoiding long-term charging or over-discharging, etc.

2. Short Circuit:
   short circuit is another common safety hazard, which may be caused by metal fragments inside the battery and damage to external element of electrical circuit. Short circuit will cause the internal temperature of the battery to rise, generate heat, and cause fire or explosion. Preventive measures include avoiding contact between the battery and metal substances and avoiding physical damage.

3. High temperature:
   high temperature is a factor that is prone to problems in lithium batteries. High temperature will cause the acceleration of chemical reactions inside the batteries and increase the risk of explosion. Preventive measures include avoiding exposure to high temperature environment, reasonable design of heat dissipation system, etc.

4. Overcharging:
   overcharging will cause excessive gas inside the battery, increase internal pressure and trigger explosion. Preventive measures include charging with overcharge protection functionDevice, regularly check the battery status, etc.

5. Improper use:
   improper use is also one of the reasons leading to potential safety hazards of lithium batteries, such as the use of unqualified chargers and excessive use for a long time. Preventive measures include selecting regular brand batteries and chargers, observing correct charging usage methods, etc.

6. Physical damage:
   lithium battery shell is very fragile. Once it is physically damaged, it may lead to internal short circuit, which may lead to fire or explosion. Preventive measures include avoiding physical damage such as collision, fall, puncture, etc., and using battery protective sleeve, etc.

Although lithium batteries have the advantages of high energy density and high performance, there are also some potential safety hazards, which need to be paid attention. By understanding the common potential safety hazards of lithium batteries and taking corresponding preventive measures, the risk of accidents can be effectively reduced and the safe use of batteries can be ensured. When using lithium batteries, users should pay attention to correct use, regular inspection, avoid excessive charging and discharging, etc., to ensure the safety of individuals and equipment. Through scientific management and preventive measures, the potential safety hazards of lithium batteries can be effectively controlled to ensure their stability and safety during use.
