摘要 用Li2MnO3和还原氧化石墨烯（rGO）对Li Mn1/3Ni1/3Co1/3O2进行表面修饰。Li2MnO3和rGO修饰可改善样品的电化学性能,其中3%Li2MnO3＋3%rGO混合修饰样品以1.0 C在2.5-4.4 V充放电,首次放电比容量为159.2 m Ah/g,循环40次的容量保持率为95.0%。 LiMn1/3Ni1/3Co1/3 O2 was surface modified by Li2MnO3 and reduced graphene oxide （rGO）. The electrochemical performance of LiMn1/3Ni1/3Co1/3 O2 was improved by Li2MnO3 and rGO modifying. The initial specific discharge capacity of 3% Li2 MnO3 ＋ 3% rGO hybrid surface modified sample was 159. 2 mAh/g when charged-discharged in 2. 5 -4.4 V at 1, 0 C, the capacity retention rate was 95.0% after 40 cycles.
