PURPOSE: An electrode material for a lithium secondary battery is provided to prevent the damage of an electrode structure due to the volume change of an electrode structure when coupled with lithium ion. CONSTITUTION: An electrode material for a lithium secondary battery includes cobalt oxide as a main ingredient. The electrode material has a conductive core material as a connection terminal and a cobalt oxide layer formed on the outer circumference of the conductive core material. The conductive core material consists of carbon fiber. The electrode structure is that the electrode materials are arranged up and down and left and right and laminated in a multilayer structure. A secondary battery includes a positive electrode using the electrode structure, an electrolyte, and a negative electrode and uses the oxidation reaction of lithium and the reduction reaction of lithium ions. |
