Title:
POLYMER, CONDUCTIVE SLURRY, POSITIVE ELECTRODE PLATE, SECONDARY BATTERY AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/082336
Kind Code:
A1
Abstract:
The present application relates to a polymer, a conductive slurry, a positive electrode plate, a secondary battery and an electric device. The polymer comprises a structural unit as shown in formula (1) and a structural unit as shown in formula (2). In formula (2), R1, R2 and R3 are each independently selected from a hydrogen atom, a halogen atom or a substituted or unsubstituted C1-C10 alkyl group. The polymer in the embodiments of the present application has good dispersity, and can be used as a dispersing agent when the polymer is applied to a secondary battery, particularly in the preparation of a conductive slurry, such that particles in the slurry are not prone to agglomeration and can be uniformly dispersed, thereby ensuring the electrochemical performance of a secondary battery.
