Abstract

The synthesis,characterization and electrochemical property of K₂FeO₄ for positive materal of lithium ion battery were studied. K₂FeO₄ with low purity was gained through the reaction of KCIO and Fe(NO₃)₃ in KOH solution and after recrystalization the purity of K₂FeO₄ reached 97%～98%. The methods of XRD and FTIR were used to measure the structure of K₂FeO₄ and its initial discharge performance was tested.
