| 摘要 |
The present invention provides an electrochemical element electrode material that makes it possible to obtain an electrochemical element having both low internal resistance and high capacity, in particular to obtain an electrochemical element electrode having a uniform active material layer in roll molding at a high rate, and an electrode formed of the electrode material. The electrochemical element electrode material comprises composite particle (a) comprising electrode active material, electric conductive material, and fluororesin (a) having a structure unit obtained by polymerizing tetrafluoroethylene and having a melting point of 200° C. or higher, and amorphous polymer (b) not having a structure unit obtained by polymerizing tetrafluoroethylene and having a glass transition temperature of 180° C. or lower.
