▎ 摘　　要

NOVELTY - A three-dimensional negative electrode material with solid electrolyte interface is prepared by loading three-dimensional carbon material with graphitic carbon nitride, then placing in molten lithium, and leaving still at high temperature. USE - The three-dimensional negative electrode material with solid electrolyte interface is useful for lithium-metal battery e.g. lithium-ion battery. ADVANTAGE - The three-dimensional negative electrode material has excellent mechanical performance and ion-conducting and electron-blocking effects, effectively reduces the partial current density on the surface of lithium metal negative electrode, avoids the growth of lithium dendrites caused by continuous deposition of lithium ions on the electrode surface, improves the performance of lithium-metal battery, and reduces the problem of loss of lithium source caused by natural solid electrolyte interface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the three-dimensional negative electrode material with solid electrolyte interface.
