摘要：

The electrochemical stability of LiNi0.5Co0.5VO4 is improved by sol-gel coating with an amorphous SiO2 film. This limits direct contact between LiNi0.5Co0.5VO4 and electrolyte, and thus, effectively provides the structural stability for the electrochemically active intercalation compound LiNi0.05Co0.5VO4, resulting in improved specific capacity and cycling performance.
