Abstract

Cathode material of LiNi_0.85Co_0.10(TiMg)_0.025O₂ were prepared by solid state reaction at 725℃ for 24 h from LiOH·H₂O, Ni₂O₃, Co₂O₃, TiO₂ and Mg(OH)₂ under flowing oxygen, and were characterized by TG-DTA, XRD, SEM and electrochemical tests. Effort to simultaneously doped LiNiO₂ with Co-Ti-Mg has been tried to improve the cathode performance. The results show that co-doping definitely has a large beneficial effect in increasing the capacity (182.7mAh/g of the first discharge capacity for LiNi_0.85Co_0.10(TiMg)_0.025O₂ and cycling behavior (175.5 mAh/g after 10 cycles). This cathode materials can be applied for lithium-ion batteries.
