▎ 摘　　要

NOVELTY - Preparation of anode involves uniformly mixing nanoactive material, conductive agent and adhesive, adding dispersant continuously, grinding, cutting and dispersing by high-speed mixer to obtain electrode slurry, placing in needle cylinder for printing, using extrusion type three-dimensional printing technology, controlling extruding path by digital program, preparing three-dimensional electrode, freezing and drying, and processing. USE - Preparation of anode used for three-dimensional printing zinc-ion battery (claimed). ADVANTAGE - The anode material is self-supporting, has excellent flexibility and capacity, does not require current collector and achieves high loading amount of active substance.
