NOVELTY - Preparing composite anode of all-solid-state lithium ion battery involves mixing an anode material, an inorganic solid electrolyte, a conductive agent and a bonding agent to obtain a mixture. The mixture is sprayed on a surface of a substrate to obtain a full-solid lithium ion battery composite anode. The temperature in a spraying process is 100-500 degrees centigrade. The pressure in the spraying process is about 0.5-2MPa. The anode material is selected from a group consisting of a lithium ion battery or a lithium ion battery. USE - Method for preparing composite anode of all-solid-state lithium ion battery. ADVANTAGE - The method enables to prepare full-solid lithium ion battery composite anode with better effect of avoiding the generation of the physical interval, so as to fully transmit the lithium ion and solving the problem that the anode lithium ion conductivity is low in the full-solid battery.
