How to Understand and Choose a 12V LiFePO4 Battery
What is a 12V LiFePO4 Battery and How Does it Work?
A 12V LiFePO4 battery operates by facilitating the movement of lithium ions between the anode (typically graphite) and cathode (lithium iron phosphate) during charging and discharging. When charging, lithium ions move to the anode, storing energy. During discharge, these ions flow back to the cathode, releasing electrical energy for use.
