Negative electrode and method for producing negative electrode, and electrode binding agent

A binding agent composition containing:

• polyacrylic acid, a polyaminobenzene derivative represented by general formula (1) below and/or a self-condensation product of the polyaminobenzene derivative, a cellulose derivative, and water;
• or
• a precursor of a compound to be obtained through condensation of the polyacrylic acid and the polyaminobenzene derivative and/or a self-condensation product of the polyaminobenzene derivative, a cellulose derivative, and water,
• wherein, in general formula (1), R is each independently selected from alkyl optionally substituted with a substituent group, alkoxy, halogen, OH, SH, NO2, CN, CO2H, SO3H, or CONH2, and
• m is an integer from 2 to 6, n is an integer from 0 to 4, and m+n≤6.
