Chemical Composition and Structure

Lithium iron phosphate batteries are composed of several key components:

Cathode: Lithium iron phosphate (LiFePO4), which provides the battery's high thermal stability and long cycle life.
Anode: Graphite, which stores lithium ions during charging and releases them during discharge.
Electrolyte: A lithium salt solution that facilitates the movement of lithium ions between the cathode and anode.
Separator: A porous membrane that prevents short circuits while allowing the passage of lithium ions.
