▎ 摘  要

NOVELTY - A cathode slurry, comprises: active substances, nanowires, conductive agents, thickeners, binders, defoamers and solvents; The nanowire is 0.3-10 pts. wt., 1-20 pts. wt. conductive agent, 3-5 pts. wt. thickener, 4-6 pts. wt. binder, 1-3 pts. wt. defoamer and 180-200 pts. wt. solvent. USE - Cathode used in preparation of cathode slurry material for preparing cathode and ion lithium used in automobile and electronic product. ADVANTAGE - The cathode slurry improves the conductivity of the cathode layer and cathode , and improves the charging and discharging efficiency and cycle lithium of the ion battery. The nano-wire in the slurry formed of the active material layer can form interweave, long connected conductive network, realizing better connection of the particles of cathode active substance, so that the loose particles can still keep the electric contact, reducing the void ratio, improving the charging or discharging lithium of ion battery, good circulation stability, and the battery in the circulation process of battery internal resistance can be better maintained. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a method for preparing the cathode slurry material; and (2) lithium ion battery.
