Abstract: The present invention relates to an electrode binder for a secondary battery, comprising: a polymer which is suitable for the reversible absorption/desorption of lithium, and which has a cohesion force to (metalloid) metallic electrode active material of 100 gf/cm or greater, and an adhesion force to an electrode collector of 0.1 to 70 gf/mm. The polymer is one or more selected from the group consisting of polyamide imide, polyamide, polyacrylonitrile, polyacrylic acid, and polyvinyl alcohol. The present invention also relates to an electrode for a secondary battery comprising said electrode binder for a secondary battery, and to the secondary battery.
