Title: BINDER FOR NONAQUEOUS SECONDARY BATTERY ELECTRODES, SLURRY FOR NONAQUEOUS SECONDARY BATTERY ELECTRODES, ELECTRODE FOR NONAQUEOUS SECONDARY BATTERIES, AND NONAQUEOUS SECONDARY BATTERY
Abstract:
Provided is a binder for electrodes, which has excellent dispersibility and enables the preparation of a slurry for electrodes, said slurry being capable of enabling a secondary battery to exhibit excellent output characteristics and excellent high-temperature cycle characteristics. A binder for electrodes according to the present invention contains a polymer and an organic solvent; and the polymer contains from 45% by mass to 69.9% by mass (inclusive) of a structural unit derived from a monofunctional ethylenically unsaturated carboxylic acid ester monomer, from 30% by mass to 54.9% by mass (inclusive) of a structural unit derived from an aromatic vinyl monomer and from 0.1% by mass to 10% by mass (inclusive) of a structural unit derived from an ethylenically unsaturated nitrile monomer.
