How LiFePO4 Batteries Work
Charging Process
The charging process of LiFePO4 batteries is straightforward and efficient. When you charge these batteries, lithium ions move from the cathode to the anode. This movement occurs through the electrolyte, a medium that facilitates ion transfer. LiFePO4 batteries support fast charging, allowing you to replenish energy quickly. This feature proves beneficial in applications where time is of the essence, such as in electric vehicles or portable power stations like the AFERIY Portable Power Station.
Discharging Process
During the discharging process, the flow of lithium ions reverses. The ions travel from the anode back to the cathode, releasing energy in the process. This energy powers your devices, providing a reliable source of electricity. LiFePO4 batteries maintain consistent power output even at low battery levels, ensuring your devices operate smoothly. The low self-discharge rate means these batteries retain their charge for extended periods when not in use, making them a dependable choice for various applications.
