Lithium Ion Polymer Battery

Polymer lithium-ion batteries offer better safety performance compared to ordinary lithium-ion batteries. In situations such as overcharging or short-circuiting, ordinary lithium-ion batteries may experience internal temperature increases, decomposition of cathode materials, and oxidation of anode and electrolyte materials. These issues can lead to gas expansion and increased internal pressure, which may result in an explosion when the pressure reaches a critical level. In contrast, polymer lithium-ion batteries use a gel electrolyte, which does not produce a significant amount of gas from liquid boiling. This design effectively reduces the risk of violent explosions.
