ACTIVE MATERIAL PARTICLE FOR ELECTRODE, ELECTRODE, ELECTROCHEMICAL DEVICE, AND PRODUCTION METHOD OF ELECTRODE

摘要

An active material particle for electrode includes an active material body 4, and a conductive aid 6 with electron conductivity partially covering a surface of the active material body 4, a projection 8 comprised of the conductive aid 6 is formed on the surface of the active material body 4, and a height of the projection 8 from the surface of the active material body 4 is not less than 5% nor more than 30% of a particle size of the active material body 4.
