Electrochemical element electrode binder, electrochemical element electrode particle composite, electrochemical element electrode, electrochemical element, and method for producing electrochemical element electrode

摘要

The purpose of the present invention is to provide a binder for use in electrochemical device electrodes which, by virtue not producing a slurry during electrode layer formation, has excellent productivity of electrodes and which, by virtue of not requiring a water-soluble polymer component as a dispersant, enables lower resistance and has excellent flexibility and accuracy of thickness of the obtained electrode; and also to provide an electrode composite using said binder, an electrode, an electrochemical device, and an electrochemical device manufacturing method. The present invention relates to a binder for use in electrochemical device electrodes which comprises a polymer with a glass transition temperature of 35-80°C and a D50 average particle diameter of 80-1000nm based on volume of the primary particles, has a volatile component at 120°C of less than 1 wt%, and consists of powder-form composite particles.
