NEGATIVE ELECTRODE PLATE, BATTERY CELL, BATTERY, AND ELECTRIC APPARATUS

Abstract

Embodiments of this application provide a negative electrode plate, a battery cell, a battery, and an electric apparatus. The negative electrode plate includes a negative electrode current collector and a negative electrode film layer disposed on at least one side of the negative electrode current collector; where the negative electrode film layer includes a negative electrode active material and a binder, the negative electrode active material includes a silicon-based material, and the binder includes at least one of the following functional groups: hydroxyl, carboxyl, amino, cyano, ester, or vinyl. The technical solution of this application can improve cohesion and adhesion of the negative electrode plate, reducing powder shedding and demolding during production, thereby enhancing cycling performance of the battery.
