▎ 摘  要

NOVELTY - Preparing anode slurry comprises (i) dry mixing the anode active material and the conductive agent to obtain a dry powder mixture; (ii) mixing the agglomerant and solvent uniformly to obtain the agglomerant solution; (iii) adding the first part of agglomerant solution into the dry powder mixture, and stirring and kneading to obtain the first mixed material; (iv) adding the second part of the agglomerant solution into the first mixture, and stirring and dispersing to obtain the second mixture; and (v) adding the solvent into the second mixed material, and stirring and dispersing. USE - The method is useful for preparing anode slurry is useful in anode sheet (claimed) is useful in lithium battery industry, industrial intelligence, military equipment informatization, smart city, universal interconnection, sharing economic, public health and fast development of people life intelligent. ADVANTAGE - The method: can disperse the slurry uniformly with better consistency, improve the powder dropping problem of the coated pole piece and peeling force of the pole piece; and shortens the flow of the anode homogenization process; and reduces the time cost of preparing the anode slurry. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Anode slurry, prepared as mentioned above; and Anode sheet.
