Facile synthesis of Co-doped VO2 (B) as the Cathode Material for Lithium-Ion Batteries with Enhanced Electrochemical Performance

Year: 2019

Type: article

Abstract: Recently, VO2 (B) has received increasing attention due to its unique layered structure in lithium-ion batteries (LIBs). However, little study is focused on the effect of transition metal doping on its electrochemical performance. Herein, Co-doped VO2 (B) electrode materials were fabricated via a facile and controllable hydrothermal method. The as-prepared electrode show an excellent electrochemical performance. When employed as cathodes for LIBs, the capacity retention of the Co0.02V0.98O2 (B) can keeps 54.1% after 100 cycles at 0.1 C, i.e., 36 mA h g -1 larger than that for the pristine. The good electrochemical performance of the composites indicates their high potential as an electrode material for LIBs.
