TETNTEK Portable Stacked LiFePO4 Battery 1. Much Safety: Using the solid electrolyte in solid-state batteries is non-flammable, hence they are less prone to catch fire. The solid electrolyte is more stable and less prone to overheating. 2. Longer Cycle Life: Having a longer cycle life, hence it can withstand a greater number of charge-discharge cycles which can improve the overall lifespan of the battery. 3. Faster Charging: Having faster charging capabilities. The absence of a liquid electrolyte reduces the risk of side reactions and allows for faster ion transport within the battery, leading to quicker charging times. 4. Reduced Environmental Impact: Solid-state batteries may use less toxic or more abundant materials, reducing the environmental impact of battery production and disposal. 5. Wide Operating Temperature Range: Solid-state batteries are suitable for using in extreme conditions, such as very high or low temperatures.
