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).
A lithium iron phosphate (LFP) battery is one type of lithium-ion (Li-ion) battery. Lithium-ion batteries are an important component of energy storage systems used in various applications such as electric vehicles and portable electronics. There are many chemistries of Li-ion battery, and LFP, NMC, LMO, and NCA are four commonly used types.

The same principle as in a Daniell cell, where the reactants are higher in energy than the products, 18 applies to a lithium-ion battery; the low molar Gibbs free energy of lithium in the positive electrode means that lithium is more strongly bonded there and thus lower in energy than in the anode.
