Abstract
A water-based, carbon filler-dispersed coating formulation for forming a conductive coating film contains (1) a hydroxyalkyl chitosan as a resin binder, (2) a conductive carbon filler, and (3) a polybasic acid or its derivative in a water-based medium containing at least water as a polar solvent. In 100 parts by mass of the coating formulation, the hydroxyalkyl chitosan (1) is contained in a range of from 0.1 to 20 parts by mass, and the conductive carbon filler (2) is contained in a range of from 1 to 30 parts by mass. An electricity-imparting material, an electrode plate for an electricity storage device, a process for producing the electrode plate, and the electricity storage device are also disclosed.
