Abstract:
1. A composition for electrode formation, comprising: a dispersion medium; metal nanoparticles dispersed in the dispersion medium; and one or more organic polymers selected from the group consisting of polyvinylpyrrolidone copolymers and cellulose ethers, wherein, a quantity of the metal nanoparticles within the composition is in a range from 2.5 to 95.0% by weight relative to 100% by weight of a dispersion composed of the metal nanoparticles and the dispersion medium, the metal nanoparticles have been chemically modified with a protective agent having an organic molecular main chain in which a carbon skeleton contains from 1 to 3 carbon atoms, a coating formed by applying the composition to a substrate using a wet coating method, the substrate includes at least one of; the protective agent is configured to be at least one of eliminated and decomposed by heat applied for calcining the coating at a temperature of 130 to 400° C., whereby organic materials having an adverse effect on an electrical conductivity are removed from the coating, and the calcined coating formed by the composition has a thickness within a range of 0.1 to 2.0 μm, a resistivity of 2.1×10
