▎ 摘　　要

NOVELTY - A slurry comprises main agent (A) and synergist (B). The main agent (A) contains active material, conductive substance, and binder, and the synergist (B) contains binder additive, wetting agent and dispersing agent. The binder additive is imide structure-containing polymer, the wetting agent is amino alcohol compound and the dispersing agent is cellulose derivative. USE - Slurry for positive electrode sheet used for secondary battery (all claimed). ADVANTAGE - The agglomerant comprises each component in a reasonable content range in the positive electrode composition, which can increase the dispersibility of the active material and the conductive material, the flexibility of the electrode is effective, can solve the problem that the thick coating electrode portion is cracked when thick coating is performed, and the energy density of the battery can be increased by using thick coating film layer. The positive electrode improves the cycle performance of the capacity conservation rate after the cycle of the secondary battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for positive electrode sheet.
