摘要/Abstract

摘要： 在恒定pH值下将层状钴铝双羟基复合金属氧化物（CoAl-LDH）均匀包覆在球状Ni(OH)₂表面，与LiOH.H₂O混合均匀后，经高温煅烧制得钴铝酸锂包覆镍酸锂0.08LiCo_0.75Al_0.25O₂-0.92LiNiO₂正极材料. 电化学测试表明，0.08LiCo_0.75Al_0.25O₂-0.92LiNiO₂正极比容量高，具有良好的倍率性能和循环寿命，其0.1C放电比容量为211 mAh.g^-1，0.5C放电比容量为195.6 mAh.g^-1，3C放电比容量为161 mAh.g^-1，0.5C 30周期循环后容量保持率为93.2%，明显优于LiNiO2和钴酸锂包覆镍酸锂0.08LiCoO₂-0.92LiNiO₂正极.

Abstract: CoAl-LDH or Co(OH)₂ coated spherical Ni(OH)₂ precursors were obtained via a co-precipitation method at a constant pH. The mixtures of the precursors and LiOH.H₂O were annealed at high temperature in O₂ atmosphere, and then the cathode materials of 0.08LiCo_0.75Al_0.25O₂-0.92LiNiO₂, 0.08LiCoO₂-0.92LiNiO₂ and LiNiO₂ were synthesized. Effects of the coating layer were also studied. The results showed that the 0.08LiCo_0.75Al_0.25O₂-0.92LiNiO₂ material possessed the best rate and cycle life performance. The discharging capacities at 0.1C, 0.5C and 3C were 211 mAh.g^-1, 195.6 mAh.g^-1 and 161 mAh.g^-1, respectively, and the capacity retention ratio after 30 cycles at 0.5C was 93.2 %. These performances were much better than those of both pure LiNiO₂ and 0.08LiCoO₂-0.92LiNiO₂.
