▎ 摘　　要

NOVELTY - Three-dimensional (3D) printing ink anode comprises 40-85 wt.% anode active material, 2-15 wt.% agglomerant and 5-30 wt.% solvent. The agglomerant is polyvinyl pyrrolidone, polyethylene glycol, hydroxypropyl cellulose, hydroxyethyl cellulose, carboxymethyl cellulose, polyacrylic acid and/or polyacrylate. USE - The anode is useful in lithium-ion battery, preferably anode, cathode, battery separator and electrolyte (claimed), electric automobile, energy storage, 3c product, electric tool and other fields. ADVANTAGE - The 3D printing anode has high electrochemical performance, overcomes the deficiency of the existing technology for preparing lithium-ion battery, reduces the dosage of the adhesive agent at the same time based on the used bonding material agent, saves the use of the conductive component agent not the necessary component, and improves the proportion of the active material anode. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: forming method of 3D printing anode; and 3D printing anode.
