ELECTRODE MATERIAL, METHOD FOR PRODUCING THE SAME, ELECTRODE, AND BATTERY

摘要

Disclosed is an electrode material containing an electrode active material, and a carbonaceous coating film covering the electrode active material and containing sulfur. Also disclosed is an electrode material which contains secondary particles each including a plurality of primary particles which are composed of the electrode active material. Each primary particle is covered with a carbonaceous coating film, and the carbonaceous coating film also lies between the primary particles. This electrode material is characterized in that the carbonaceous coating film contains sulfur.
