Abstract

To provide a method for producing slurry that can form an active material layer having low resistance.SOLUTION: The method for producing the slurry includes: a first mixing step of mixing a carbon agent and a binder, and obtaining a first mixture; a second mixing step of mixing the first mixture and active material particles, kneading the materials, and obtaining a second mixture; and a third mixing step of mixing the second mixture and a solvent. The carbon agent is at least one selected from the group consisting of carbon nanoparticles and carbon black particles.SELECTED DRAWING: Figure 3
