发明名称 Positive electrode material of Li-ion secondary battery
摘要 A positive electrode material of a Li-ion secondary battery is disclosed. This positive electrode material has a formula of Li1+xMn2-yMyO4-zClz, wherein M can be magnesium (Mg), aluminum (Al), chromium (Cr), iron (Fe), cobalt (Co) or nickel (Ni) ions, 0<=x<=0.4, 0<=y<=0.3, and 0.01<=z<=1.0. By means of replacing some oxygen ions of this material with chlorine ions, the crystalline structure thereof can be varied and thus longer life cycle and better stability at high temperature can be achieved.
