PRODUCTION METHOD OF BINDER COMPOSITION FOR NONAQUEOUS SECONDARY BATTERY ELECTRODE, PRODUCTION METHOD OF SLURRY COMPOSITION FOR NONAQUEOUS SECONDARY BATTERY ELECTRODE, PRODUCTION METHOD OF ELECTRODE FOR NONAQUEOUS SECONDARY BATTERY, AND PRODUCTION METHOD OF NONAQUEOUS SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a binder composition for a nonaqueous secondary battery electrode, which enables both of the achievement of the satisfactory easiness of filling an electrolyte in assembling a battery and the suppression of metal precipitation in charging the battery while retaining high adhesion in an electrode.SOLUTION: A method for producing a binder composition for a nonaqueous secondary battery electrode including a water-soluble polymer for a binder including a (meth)acrylic amide monomer unit comprises the steps of: (A) neutralizing an aqueous solution including the water-soluble polymer; and (B) filtering, by a filter medium, the neutralized aqueous solution including the water-soluble polymer to obtain the binder composition including the water-soluble polymer. The fraction of undissolved contents of 1 μm or larger in particle diameter to the total amount of solid contents in the binder composition for a nonaqueous secondary battery electrode is 0.0001 to 5.0 mass%.SELECTED DRAWING: None
