摘　　要：将LiMn2O4分别与Li2CO3、Co3O4以及Li2CO3+Co3O4混合物在800℃高温处理,利用恒电流充放电法测量了材料的比容量,经处理后材料的比容量均低于LiMn2O4的放电容量,但循环性能比处理前好;通过XRD的分析.材料的结构仍保持了尖晶石的特征。The LiMn2O4 was mixed with Li2CO3, Co3O4, Li2CO3 + Co3O4 respectively and was treated at temperature an 800℃ . The charge and discharge measurement showed that the capacity of the treated LiMn2O4 decreased while the cyclic performance was improved. XRD results showed that the treated LiMn2O4 had spinel structure characteristics.
