Advantages:
Safety:
Lower Thermal Runaway Risk: The polymer electrolyte used in these batteries has better thermal stability compared to liquid electrolytes in some other battery chemistries. This reduces the risk of thermal runaway, which could lead to dangerous situations such as fire or explosion. For example, in electric vehicles, the use of flat lithium polymer batteries with good thermal stability can enhance the overall safety of the vehicle.
No Liquid Leakage: Since there is no liquid electrolyte, there is no risk of leakage, which can damage the device or cause safety hazards. This makes them more reliable and suitable for a wide range of applications, including those where the device may be in different orientations or subjected to vibrations4.
Low Self-Discharge Rate: They have a relatively low self-discharge rate, meaning they can retain their charge for longer periods when not in use. This is beneficial for devices that are not used frequently or for backup power applications. For example, a flat lithium polymer battery-powered emergency light that is stored for long periods will still have a significant amount of charge when needed.
Good Charge and Discharge Efficiency: They can be charged and discharged relatively efficiently, with charge/discharge efficiencies typically ranging from 80% to 90%. This means that less energy is wasted during the charging and discharging process, resulting in better overall energy utilization.
