The electrochemistry of olivine-type iron phosphate (FePO₄) as a battery cathode material, in aqueous lithium hydroxide (LiOH), has been investigated. The material forms intercalated LiFePO₄ reversibly on electroreduction/oxidation. The formation of Fe₃O₄ phase, in addition to the regeneration of FePO₄ during reverse oxidation of LiFePO₄, also occurs. In this regard, the mechanism of FePO₄ discharge/charge in aqueous LiOH differs from that in non-aqueous solvents.
