▎ 摘　　要

NOVELTY - The method involves providing a three-dimensional network framework material providing porous channels, and coating graphene oxide powder on a surface of a network framework. The coated graphene oxide is partially reduced, and the three dimensional network frame-work is dipped into a graphene oxide dispersion solution. An insulating material is coated on the network framework that is provided with a network fiber. The graphene oxide comprises coarse powder having an average particle diameter of 10 to 50 micrometers. A three dimensional electrode structure is provided on a current collector. A negative electrode, electrolyte solution, a separator and a positive electrode are provided in a lithium secondary battery. USE - Method for manufacturing a three-dimensional electrode structure for a lithium secondary battery (all claimed). ADVANTAGE - The method enables maximizing an electrode position space in an inner side of a network through control of conductivity of the three-dimensional network structure. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a three-dimensional electrode structure; and a lithium secondary battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the three-dimensional electrode structure.
