摘要 以CH3COOLi、Ni(CH3COO)2和Mn(CH3COO)2为原料,用流变相法合成了正极材料ZnO包覆的Li Ni0.5Mn1.5O4。XRD测试表明:该材料为尖晶石结构。电化学性能测试表明:包覆ZnO后,Li Ni0.5Mn1.5O4在3.5~4.9 V以0.1C充放电的首次放电比容量为137.68 mAh/g,第30次循环的放电比容量为133.78 mAh/g,循环稳定性得到了改善。 Cathode material ZnO-coated LiNi0.5 M n1. 5 O4 was synthesized via rheological method with CH3 COOLi, Ni( CH3 COO) 2 and Mn(CH3COO)2 as raw materials. XRD test showed that the material was spinel structure. Electrochemical performance tests showed that after coating ZnO, the initial specific discharge capacity of LiNi0.5 Mn1.5 O4 was 137.68 mAh/g when 0.1 C chargedischarge at 3.5 -4.9 V, the specific discharge capacity at the 30th cycle was 133.78 mAh/g,its cycle stabihty was improved.
