Title:
COMPOSITION, RESIN COMPOSITION, COMPOSITION FOR POSITIVE ELECTRODE, SLURRY FOR POSITIVE ELECTRODE, POSITIVE ELECTRODE, AND SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/034901
Kind Code:
A1
Abstract:
Provided are a composition serving as a binder having an excellent balance of suppressing deterioration of battery performance in a high-capacity electrode, high-temperature storage characteristics, and direct current resistance, and a slurry for a positive electrode, a positive electrode, and a secondary battery using said composition. Provided according to the present invention is a composition in which the component ratio of the component S180 is from 10% to 80% and the relaxation time of the component S180 is 500 μsec or longer when the free induction decay curve of the composition measured at 180°C by the solid echo method using pulse NMR is separated into three components: component S180, component M180, and component H180.
