摘　　要：在空气气氛中,采用熔融盐法制备出了锂离子电池正极材料LiNiO2。差热-热重曲线分析表明:629℃就已经反应完全。XRD分析表明:700℃反应26h制得的LiNiO2具有最完整的层状结构。电性能测试表明所得正极材料放电比容量较好。In air atmosphere, using molten salt method synthesized cathode material LiNiO2 for lithium ion batteries. TG-DTA showed the reaction finished completely at 629℃. XRD results showed the prepared LiNiO2 calcined at 700℃ for 26h had perfect layer structure. Electrochemical performance tests testified that the cathode material LiNiO2 had good discharge specific capacity.
