Title:
CONDUCTIVE MATERIAL DISPERSION LIQUID, ELECTRODE PASTE, AND CONDUCTIVE MATERIAL COATING ACTIVE SUBSTANCE
Document Type and Number:
Japanese Patent JP2011070908
Kind Code:
A
Abstract:
To provide a conductive material dispersion liquid ensuring favorable dispersibility and conductivity, an electrode paste, and a conductive material active substance using the same.
The conductive material dispersion liquid contains the conductive material, a dispersant and a dispersion medium. The conductive material is carbon black which is not more than 40 nm in average primary particle size and not more than 400 nm in average dispersed particle size or carbon nanotube which is not more than 30 nm in average outer diameter and is not aggregated and is dispersed. The dispersant contains a nonionic dispersant.
