What Are the Benefits and Applications of LiFePO4 Lithium Batteries?
The LiFePO4 battery, or lithium iron phosphate battery, is a type of lithium-ion battery known for its safety, longevity, and thermal stability. It is widely used in electric vehicles, energy storage systems, and various industrial applications due to its high performance and reliability.
What is a LiFePO4 battery and how does it work?
A LiFePO4 battery uses lithium iron phosphate as its cathode material, which contributes to its unique properties such as high thermal stability and safety. When the battery discharges, lithium ions move from the anode (typically made from graphite) to the cathode, generating an electric current that powers devices.Chart: Basic Operation of a LiFePO4 Battery
