▎ 摘  要

NOVELTY - Preparing anode slurry for a lithium ion battery, comprises providing a predetermined ratio of anode active material powder, binder powder and conductive agent powder, where the predetermined ratio is 94-96:2:2-4, mixing and stirring in a water bath cooling and sealed environment to obtain the first mixture, adding an organic solvent to the first mixture, wetting the first mixture, diluting, stirring, dispersing, kneading and scraping with an organic solvent to obtain a second mixture, and degassing the second mixture under vacuum to obtain the anode slurry for the lithium ion battery. USE - The method is useful for preparing anode slurry for anode of lithium ion battery (claimed). ADVANTAGE - The anode slurry has high dispersibility, strong uniformity and viscosity and fineness in a suitable range; reduces the resistance of the electrode sheet anode coating the current collector; and improves the performance of the battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Lithium-ion battery anode slurry; and anode of electrode sheet.
