LiNixCo1-xO2的制备与性能
摘要:
采用球形Ni(OH)2和LiNO3、CoO为原料,空气气氛条件下800℃恒温8 h,合成了锂离子电池正极材料LiNixCo1-xO2。XRD分析表明,合成的LiNixCo1-xO2粉末结晶良好,具有规整的α-NaFeO2层状结构。SEM分析表明,粉末颗粒呈球形,粒径约为7 μm。充放电测试表明,合成的LiNixCo1-xO2正极材料放电比容量为152 mA·h/g,100次循环后容量保持率为80%。

Synthesis and Performance of LiNixCo1-xO2
Abstract:
The LiNixCo1-xO2 powder was synthesized by sintering spherical Ni(OH)2, LiNO3 and CoO in air at 800℃ for 8 h. XRD results showed that the powders are highly crystallized LiNixCo1-xO2 with ordered layer structure of α-NaFeO2. SEM microphotos showed the powders are spherical particulate with the particle size of ca. 7 μm. Electrochemical test proves. The discharge capacity of the cathode material was 152 mA·h/g and the capacity holding rate was 80% after 100 cycles. The cathode material has excellent electrochemical performance.
