▎ 摘　　要

NOVELTY - Preparing ion/electric field controllable three-dimensional metal anode involves adding electrophilic substance, viscous agent, conductive agent and/or active substance into solvent, and controlling ratio of each component to obtain different composition of three-dimensional printing ink. The three-dimensional printing inks of different compositions are printed into a three-dimensional current collector by a layer-by-layer three-dimensional printing method, and post-processing to obtain the product. USE - The method is useful for preparing ion/electric field controllable three-dimensional metal cathode. ADVANTAGE - The method enables to prepare three-dimensional metal cathode that improves safety and circulation stability of the metal ion battery, and has excellent cycle performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a ion field/electric field controllable three-dimensional metal cathode, is prepared as mentioned above.
