▎ 摘　　要

NOVELTY - Cathode slurry includes cathode active materials and a sacrificial dispersant, and the sacrificial dispersant is volatile during coating or baking. USE - The cathode slurry is useful in a cathode sheet and a lithium-ion battery, where the cathode includes cathode active material and sacrificial dispersant. ADVANTAGE - The inventive cathode pulp uses sacrificial dispersant to replace thickening agent to maintain the stability of the slurry, and improves the ratio of the active material cathode the solid content of cathode slurry material. The lithium-ion battery has high energy density, multiplying power performance and low temperature discharge performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a method for preparing cathode slurry; a cathode pole piece; and a lithium-ion battery.
