A lithium iron phosphate battery is a type of lithium battery that uses lithium iron phosphate as the positive electrode material. The passage further mentions other cathode materials used in lithium batteries, but the focus is on lithium iron phosphate.
As lithium ions are removed during the charging process, it forms a lithium-depleted iron phosphate (FP) zone, but in between there is a solid solution zone (SSZ, shown in dark blue-green) containing some randomly distributed lithium atoms, unlike the orderly array of lithium atoms in the original crystalline material (light blue).
Lithium iron phosphate batteries, which use LiFePO4 as the positive electrode, meet the following performance requirements, especially during high discharge rates (5-10C discharge): stable discharge voltage, safety (non-burning, non-explosive), and long life (cycle times).
Like any other battery, Lithium Iron Phosphate (LiFePO4) battery is made of power-generating electrochemical cells to power electrical devices. As shown in Figure 1, the LiFePO4 battery consists of an anode, cathode, separator, electrolyte, and positive and negative current collectors.
As shown in Figure 1, the LiFePO4 battery consists of an anode, cathode, separator, electrolyte, and positive and negative current collectors. The positive terminal of a battery is called the cathode, whereas the negative terminal is termed as the anode. The anode terminal acts as the source of lithium ions.
The membrane is made of a type of polymer (plastic) that has lots of tiny little pores to make it easy for the lithium ions to pass through. The battery will be fully charged when all the positive lithium ions available in the cathode terminal reach the anode terminal and are stored between layers of graphene accordingly.
