CATHODE MATERIAL PREPARATION METHOD, CATHODE MATERIAL AND LITHIUM-ION BATTERY

摘要

The invention relates to a cathode material preparation method, to a cathode material and to a lithium-ion battery. The technical result of the invention consists in increasing the capacity and number of recharge cycles of a battery. A lithium battery contains an anode made of Li metal, an electrolyte, and a cathode in the form of a metal current collector; the surface of the cathode has applied thereto a suspension with a concentration of 0.1-1 g/ml, said suspension containing a composite material which is in the form of V2O5 nanorods in a graphene shell, and which is dissolved in acetone.
