What are the advantages of lithium polymer batteries in terms of safety

　　The advantages of Li polymer batteries in terms of safety mainly benefit from their use of solid or gel like polymer electrolytes and their unique battery structure design. The following are several key factors that enable lithium polymer batteries to achieve safety advantages:

　　1. Solid or gel electrolyte:

　　The electrolyte used in lithium polymer batteries is solid or gel, rather than the liquid electrolyte commonly used in lithium ion batteries. This solid electrolyte is less prone to leakage, thus reducing the risk of electrolyte leakage caused by battery rupture or damage. Solid electrolytes are less prone to violent chemical reactions compared to liquid electrolytes under extreme conditions such as high temperatures or overcharging, thereby reducing the risk of fire or explosion.

　　2. No risk of liquid leakage:

　　Because the electrolyte is solid or gel, the lithium polymer battery does not have the problem of liquid electrolyte leakage in normal use or even in the case of damage. This reduces the risk of short circuits and chemical corrosion caused by electrolyte leakage.

　　3. Flexible shell:

　　Lithium polymer batteries typically use laminated aluminum polymer film as the outer shell, which can expand when the internal pressure of the battery increases instead of potentially exploding like hard shell batteries. When the battery overheats or experiences an internal short circuit, the aluminum-plastic film may expand or rupture, releasing pressure and thus improving safety.

　　4. Temperature control:

　　The design of lithium polymer batteries allows for better temperature control. The internal thermal management system of the battery can more effectively prevent overheating, thereby reducing the risk of thermal runaway.
