摘要
采用高温固相法合成了高钠含量的P2型层状氧化物钠离子电池正极材料Na_(0.93)Li_(0.125)Ni_(0.25)Mn_(0.45)Ti_(0.125)Zn_(0.05)O_(2)(NLNMTZ).研究发现,该材料电化学曲线平滑,表现出良好的循环稳定性和出色的倍率性能.在20 mA/g下,容量高达117.6 mAh/g;在200 mA/g下,700次循环后容量保持率为80%.
The P2-type layered oxide sodium-ion battery cathode material with high Na-content, Na_(0.93)Li_(0.125)Ni_(0.25)Mn_(0.45)Ti_(0.125)Zn_(0.05)O_(2)(NLNMTZ) was synthesized by high temperature solid reaction.Experiments showed that the material had a smooth electrochemical profile, good cycling stability and excellent rate performance.The capacity could reach 117.6 mAh/g at 20 mA/g, and after the 700 cycles, the capacity retention rate was 80 % at 200 mA/g.
