▎ 摘  要

NOVELTY - Preparing anode slurry involves obtaining conductive adhesive by adopting first conductive agent and adhesive, where the surface hydroxyl group of the first conductive agent is bonded to the surface carboxyl functional group of the adhesive. A first slurry is obtained by adopting a lithium-supplement type silicon-oxygen material, stabilizing agent and second conductive agent, and a second slurry is obtained from the first slurry. A cathode slurry is then prepared by adopting the conductive adhesive and second slurry. USE - Method for preparing anode slurry used in negative electrode sheet of lithium battery. ADVANTAGE - The method enables to prepare cathode slurry that improves the bonding of the network structure, stable slurry viscosity, stability, homogenizing and coating effect, and improves the performance of the lithium battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) Negative electrode sheet, which is produced by the negative electrode slurry. (2) Lithium battery, which comprises the negative electrode sheet.
