BINDER FOR USE IN ELECTROCHEMICAL DEVICE ELECTRODES, PARTICLE COMPOSITE FOR USE IN ELECTROCHEMICAL DEVICE ELECTRODES, ELECTROCHEMICAL DEVICE ELECTRODE, ELECTROCHEMICAL DEVICE, AND ELECTROCHEMICAL DEVICE ELECTRODE MANUFACTURING METHOD

摘要

An object of the present invention is that the productivity of the electrode is excellent because a slurry is not prepared when forming the electrode layer, and since a water-soluble polymer component is not required as a dispersant, it is possible to reduce resistance, and the thickness accuracy and flexibility of the obtained electrode are improved. It is to provide an excellent binder for an electrochemical element electrode, a composite for an electrode using the same, an electrode, an electrochemical element, and a method of manufacturing an electrochemical element. The present invention is composed of a polymer having a glass transition temperature of 35 to 80°C, a D50 average particle diameter based on the volume of the primary particles of 80 to 1000 nm, the volatile matter at 120°C is less than 1% by weight, and powdery composite particles And relates to a binder for an electrode of an electrochemical device which is a powdery composite particle.
