Abstract

This study is to research Li$_{x}$Ni$_{2-x}$O$_2$ cathode for lithium chargeable battery. We investigated morphology and cell resistance, capacity and Ah efficiency of Li$_{x}$Ni$_{2-x}$O$_2$/Li cells using Li$_{x}$Ni$_{2-x}$O$_2$ prepared under air and $O_2$ flow. The (003)I/(104)I intensity ratio was 1.4. The cell resistance was increased with increasing Li in Li$_{x}$Ni$_{2-x}$O$_2$. The discharge capacity based on Li$_{x}$Ni$_{2-x}$O$_2$of 1st and 15th cycles was 135㎃h/g and 108㎃h/g, respectively. The Li$_{x}$Ni$_{2-x}$O$_2$ prepared with hexan under $O_2$ flow had a good properties. properties. properties.
