▎ 摘  要

NOVELTY - Sodium ion battery anode slurry comprises 48-48 wt.% anode active substance, 1.3-1.8 wt.% adhesive, 0.5-1 wt.% conductive agent, 0.1-0.8 wt.% inhibitor, 0.1-0.5 wt.% dispersant and 48-52 wt.% solvent. The conductive agent is conductive carbon black, cnt conductive paste or graphene conductive paste. The inhibitor is oxalic acid or maleic anhydride. The adhesive is polyvinylidene fluoride. The dispersant is polyvinylpyrrolidone. The solvent is Nmethyl pyrrolidone. USE - Sodium ion battery anode slurry. ADVANTAGE - The sodium ion battery anode slurry improves the slurry fluidity, inhibits the high alkalinity slurry of gelation and agglomeration of small particle size particles, at the same time, optimizes the sizing preparation, the high productivity preparation has good dispersion effect, and has better property of processing, and the preparation performance is higher. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the sodium ion battery anode slurry.
