▎ 摘  要

NOVELTY - A negative electrode slurry comprises 35-45 wt.% negative active material, 2-5 wt.% negative electrode conductive agent, 1-5 wt.% binder and 35-45 wt.% solvent, where the negative electrode conductive agent is selected from the group carbon black aggregates, single-walled carbon nanotubes and graphene, and the carbon black aggregate has a particle diameter of 40-600 nm and specific surface area of 100-300 m2/g, the single-walled carbon nanotube has a diameter of 0.4-5 nm and tube length of greater than or equal to 30 mu m, and the graphene has a layer number of less than or equal to 10 layers and specific surface area of greater than or equal to 500 m2 /g. USE - Negative electrode slurry for lithium battery. ADVANTAGE - The negative electrode slurry improves battery performance and cycle performance, and improves the energy density of the lithium battery.
