Abstract

See full text

An electrode material which can improve the mobility of electrons and the mobility of ions at the same time, and, furthermore, does not have a problem of the impairment of the diffusion of lithium ions in a thin layer containing a carbonaceous electron-conductive substance so as to be excellent in terms of load characteristics and energy density, and an electrode and a lithium ion battery are provided. The electrode material of the invention is produced by forming a thin layer made of a carbonaceous electron-conductive substance on surfaces of primary particles made of an electrode active material, in which the carbonaceous electron-conductive substance contains nitrogen atoms.
