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.
