<P>PROBLEM TO BE SOLVED: To provide an electrochemical element electrode material which allows for production of an electrochemical element combining a low internal resistance and a high capacity, especially allows for production of an electrochemical element electrode having a uniform active material layer in roll forming at high forming speed, and to provide an electrode formed of that electrode material. <P>SOLUTION: The electrochemical element electrode material contains composite particles (α) which contains (a) a fluororesin including a structural unit formed by polymerizing an electrode active material, a conductive material and tetrafluoroethylene and having a melting point of 200°C or higher, and (b) an amorphous polymer not including a structural unit formed by polymerizing tetrafluoroethylene and having a glass transition temperature of 180°C or lower. This material is obtained by such a method as spray-drying and granulating a slurry dissolved into a solvent. <P>COPYRIGHT: (C)2012,JPO&INPIT |
