    Abstract

    The electrochemistry of olivine-type iron phosphate (FePO 4) as a battery cathode material, in aqueous lithium hydroxide (LiOH), has been investigated. The material forms intercalated LiFePO 4 reversibly on electroreduction/oxidation. The formation of Fe 3O 4 phase, in addition to the regeneration of FePO 4 during reverse oxidation of LiFePO 4, also occurs. In this regard, the mechanism of FePO 4 discharge/charge in aqueous LiOH differs from that in non-aqueous solvents.
