Title:
BINDER AND RELATED SEPARATOR, ELECTRODE SHEET, BATTERY, BATTERY MODULE, BATTERY PACK AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/178690
Kind Code:
A1
Abstract:
The present application provides a binder, and a separator and an electrode sheet comprising same, as well as a related secondary battery, a battery module, a battery pack, and an electric device. The binder comprises an organic polymer and an inorganic substance. The organic polymer is obtained by polymerizing a first polymer monomer having an ester bond, a second polymer monomer having a nitrile bond, and a third polymer monomer having an amide bond, wherein a weight ratio of the first polymer monomer to the second polymer monomer to the third polymer monomer is 1:0-0.8:0-0.15, optionally, 1:0.05-0.2:0.05-0.1. When the binder is applied to a separator, the resistance of the separator is reduced, the ionic conductivity of the separator is improved, and the battery performance is improved.
