<p>PROBLEM TO BE SOLVED: To provide an electrode material which allows for production of a power storage device having a large charge/discharge capacity.SOLUTION: An electrode material having a specific surface area of 500 m/g or less is obtained via a process for heating a raw material, containing a solvent extract of coal, at 700-2,500°C under an atmosphere substantially not containing oxygen. Alternatively, an electrode material containing at least one kind selected from a group consisting of a metal capable of absorbing lithium, semimetals and their oxides is obtained via a process for heating a raw material, containing a solvent extract of coal under an atmosphere substantially not containing oxygen.</p> |
