NOVELTY - High surface density cathode sheet comprises 95-98 wt.% cathode active substance, 0.1-2 wt.% binder and 0.1-2 wt.% thickener. USE - High surface density cathode sheet for lithium-ion battery. ADVANTAGE - The high surface density cathode sheet improves the flexibility of the pole piece, so as to solve the problem that the pole baking process is turned edge, cracking, falling powder and so on, improving the production efficiency of the electric core preparation, capable of improving the solid content of the cathode, reducing the baking temperature of pole piece, can improve polymer wettability and dispersibility, improve the adhesion, and improve the flexibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the high surface density cathode sheet.
