Abstract

A conductive auxiliary agent for an electrode slurry for a battery. The electrode slurry contains an electrode active material and a conductive auxiliary agent, and is applied to a sheet-shaped current collector. The conductive auxiliary agent is a carbon paste produced by dispersing a carbon powder in a solvent. The carbon paste has a viscosity of at least 20 Pa·s and not more than 40 Pa·s. The carbon material can be acetylene black.
