Abstract
An electrode mixture paste for a sodium secondary battery contains a positive electrode active material capable of being doped and dedoped with a sodium ion, an electroconductive material, a binder, an organic solvent, and an acid having a valence number of 2 or more. The electrode mixture paste for a sodium secondary battery gives little change in viscosity with lapse of time even when there are no special facilities.
