摘要：

Single phase stoichiometric spinel LiMn2O4 and oxygen defect spinel Li1+xMn2-xO4-x has been successfully prepared and its discharge capacity is discussed theoretically. This defect spinel shows discharge plateaux with equivalent capacity at ca. 4.4 and 3.2 V. It is proved that the discharge capacity at 3.2 V is tightly related to oxygen defect content, z, by the slope analysis.
