LiZnxNi0.5-xMn1.5O4　(0.01&lex&le0.09)　as　cathode　materials　of　lithium　ion　battery　were　synthesized　by　methods　of　coprecipitation　and　sol-gel.　X-ray　powder　diffraction　showed　that　a　single　spinel　phase　can　be　obtained　by　heating　the　precursor　at　lower　temperature.　Charge/discharge　experiments　of　Li/LiZnxNi0.5-xMn1.5O4　batteries　showed　that　synthetic　method　and　heat-treatment　process　had　a　determined　effect　on　the　performances　of　the　materials.　Charge/discharge　plateaus　can　be　found　only　at　a　potential　around　4.7V,　which　indicated　that　only　Ni2+Ni4+　transformation　occurred　during　charge/discharge　process.　The　specific　capacity　of　LiZnxNi0.5-xMn1.5O4　in　the　1st　cycle　reached　its　theoretical　value　and　decreased　with　the　increasing　value　of　x.　The　results　of　half-cell　tests　also　showed　that　the　cyclability　of　LiZnxNi0.5-xMn1.5O4　need　to　be　improved.
