Preparation and Characterization of LiNi_(0.85)Co_(0.10)(TiMg)_(0.025)O_2  as Cathode Materials for Lithium-ion Batteries

Abstract

Abstract: Cathode material of LiNi_(0.85)Co_(0.10)(TiMg)_(0.025)O_2 were prepared by solid state reaction at 725℃ for 24 h from LiOH·H_2O, Ni_2O_3, Co_2O_3, TiO_2 and Mg(OH)_2 under flowing oxygen, and were characterized by TG-DTA, XRD, SEM and electrochemical tests. Effort to simultaneously doped LiNiO_2 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_(0.85)Co_(0.10)(TiMg)_(0.025)O_2) and cycling behavior (175.5 mAh/g after 10 cycles). This cathode materials can be applied for lithium-ion batteries.

Key words: Lithium-ion batteries, Cathode materials, LiNi_(0.85)Co_(0.10)(TiMg)_(0.025)O_2, Co-doping
