▎ 摘　　要

NOVELTY - The method involves adding carbon nanotubes and additives. A carbon nano-fiber-graphene aqueous suspension is obtained. A carbon nanophraphene anhydrous suspension is added into a metal plating solution. A mixed solution is formed. Metal ions are utilized in the metal plating solution as metal and an anode. A cathode of a current collector is utilized as the cathode. A mixed solution is taken as an electrolyte and an electrode position. An electro-deposition cathode is obtained with a 3D spherical shape on a surface of the current collector. USE - Method for preparing a cathode collector with surface presenting three-dimensional spherical shape. ADVANTAGE - The method enables ensuring excellent conductivity and high specific surface area, improving electrochemical performance and bonding performance between the current collector and active material of load. The method enables realizing large-scale industrial production and popularization process in a simple manner. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: 1. an electrode; and 2. a battery. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a method for preparing a cathode collector with surface presenting three-dimensional spherical shape.
