LiMg_0.1Co_0.9BO₃ as a positive electrode material for Li-ion batteries.

ABSTRACT: LiCoBO₃ could be a promising cathode material given the electronic and ionic conductivity problems are addressed. Here, Mg substitution in LiCoBO₃ is employed to stabilise the structure and improve the electrochemical performance. LiMg_0.1Co_0.9BO₃ is synthesised for the first time via sol-gel method and Mg substitution in the structure is verified by X-ray powder diffraction and energy dispersive X-ray analyses. The electrochemical properties are investigated by galvanostatic cycling and cyclic voltammetry tests. The composite electrode with conductive carbon (reduced graphite oxide and carbon black) delivers a first discharge capacity of 32 mA h g^-1 within a 4.7-1.7 voltage window at a rate of 10 mA g^-1.
