(57) [Abstract] [PROBLEMS] To provide a battery having a large initial capacity and a small decrease in capacity. An ethylenically unsaturated monomer mixture containing an ethylenically unsaturated carboxylic acid (for example, methacrylic acid 20 Parts by weight, styrene 10 parts by weight, methyl methacrylate 70 Resin (A) 20-90 obtained by at least partially neutralizing a resin having an acid value of 50-300 obtained by copolymerizing (part by weight of a mixture). An unsaturated monomer mixture (B) comprising a diene monomer and an ethylenically unsaturated monomer in an aqueous medium in the presence of 0 part by weight (for example, 30 parts by weight of butadiene and 35 parts of styrene). Parts by weight, 35 parts by weight of methyl methacrylate) 10 A slurry prepared by mixing 0 parts by weight of latex particles dispersed in a solvent in a binder composition for a battery and an active material (for example, carbon as a negative electrode active material) is applied to an electrode substrate to remove the solvent to form an electrode. , Manufacture batteries. |
