▎ 摘　　要

NOVELTY - Multifunctional additive comprises 3-5 wt.% conductive agent, 0.2-2 wt.% fast ion conductor material, 0.1-1.2 wt.% dispersant, and N-methylpyrrolidone (remaining amount). USE - The multifunctional additive is useful for anode of lithium ion battery. ADVANTAGE - The multifunctional additive: has dual functions of improving electronic conductivity and ion conduction rate, and avoids structural damage to the anode material during the coating process, at same time, high-pressure micro-jet technology realizes the efficient dispersion of fast ion conductors, and blocks the agglomeration of conductive agents e.g. graphene and carbon nanotubes, which greatly improves the dispersibility and stability of the slurry. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) Preparing the multifunctional additive; and (2) Lithium ion battery.
