▎ 摘　　要

NOVELTY - Preparing three-dimensional selfsupporting current collector, prepared by the lithium-philic metal oxide material and conductive material by wet spinning technology. USE - Preparation method of three-dimensional self-supporting current collector used in lithium battery. Can also be used in portable electronic product, electric automobile, wide application and rapid development of intelligent power grid. ADVANTAGE - The method is simple and controllable, easy to scale production, by adjusting the wet spinning condition, adjustable fiber diameter of the composite fiber film, specific surface area, porosity and so on. The prepared current collector has good lithium and conductivity, which can effectively reduce the local current density, realize the uniform deposition of the lithium and relieve the growth of lithium dendritic crystal, which is good for improving the stability and safety of the metal battery lithium. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: A three-dimensional self-supporting current collector; A lithium metal electrode; and A lithium metal battery. DESCRIPTION OF DRAWING(S) - The drawing shows a three-dimensional self-supporting current collector preparation flow diagram. (Drawing includes non-English language text).
