Title:
NEGATIVE ELECTRODE PLATE, SECONDARY BATTERY AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/082277
Kind Code:
A1
Abstract:
Provided in the present application are a negative electrode plate, a secondary battery and an electric device. The negative electrode plate comprises a negative electrode current collector and a negative electrode film layer arranged on at least one surface of the negative electrode current collector, wherein the negative electrode film layer comprises a negative electrode active material and a blended polymer, the blended polymer comprising a π conjugated polymer and a polymer containing an ester group. By adding the blended polymer into the negative electrode film layer in the present application, the dynamic performance of the secondary battery can be improved, thereby improving the charge-discharge rate performance and cycling stability of the secondary battery.
