▎ 摘　　要

NOVELTY - Preparing anode material comprises measuring raw materials based on mass content of active material, performing secondary ball milling on sulfur-containing argentite-type sulfide solid electrolyte, and mixing and grinding all raw materials to obtain anode material, where the raw materials include sulfur-containing silver-germanium ore-type sulfide solid electrolyte, active material and conductive agent, the preparation method comprises no secondary ball milling or secondary ball milling condition is ball-to-material ratio z ≤18, or ball milling time w ≤3 hours when the mass content of the active substance is w 50-70%, the secondary ball milling condition is ball-to-material ratio z satisfies 40-18, and the ball milling time w satisfies 5-3 hours when the mass content of the active material is w 70-80%. USE - The method is useful for preparing anode material in field of lithium-ion batteries. ADVANTAGE - The method: overcome defects of poor electrochemical performance, especially poor rate performance, of all solid-state batteries in prior art. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for anode material, prepared by above method.
