ELECTRODE MATERIAL FOR LITHIUM SECONDARY BATTERY,ELECTRODE STRUCTURE COMPRISING THE ELECTRODE MATERIALAND SECONDARY BATTERY COMPRISING THE ELECTRODESTRUCTURE

摘要

PURPOSE: An electrode material for a lithium secondary battery improves charging efficiency and prevents damage on an electrode structure. CONSTITUTION: An electrode material (7) for a lithium secondary battery has a core material (C) and a silicon layer (S) formed on the outer surface of the core material. The material has a plurality of core bars are coupled to the core material. A carbon nanotube layer (9) coated with carbon nanotube is formed on the outer surface of the core material. The silicon layer is cylindrical. The core bar is formed of a conductive material or a carbon fiber. An electrode structure for a lithium secondary battery has a multilayer structure by a plurality of the electrode materials aligned left and right and up and down.
