Abstract
An electrode for a lithium ion secondary battery includes an electrode active material and a water-soluble polymer. The water-soluble polymer is a copolymer containing 1% by weight to 30% by weight of an aromatic vinyl monomer unit, 20% by weight to 60% by weight of an unsaturated carboxylic acid monomer unit, and 0.1% by weight to 5% by weight of a crosslinkable monomer unit.
