Abstract
A porous carbon material, wherein a half width (2θ) of a diffraction peak (10×) (38° to 49°) by X-ray diffraction is 4.2° or less, and wherein a ratio (mesopore volume/micropore volume) of a mesopore volume (cm3/g) measured by a BJH method to a micropore volume (cm3/g) measured by a HK method is 1.20 or more.

A porous carbon material,
- wherein a half width (2θ) of a diffraction peak (10×) (38° to 49°) by X-ray diffraction is 4.2° or less, wherein 10× means a pseudo peak observed in the vicinity of the 101 plane in graphite, and
- wherein a ratio (mesopore volume/micropore volume) of a mesopore volume (cm3/g) measured by a BJH method to a micropore volume (cm3/g) measured by a HK method is 1.20 or more, but 2.00 or less.
A porous carbon material,
- wherein the porous carbon material is subjected to heat treatment at a temperature of 1,200° C. or higher,
- wherein the porous carbon material exhibits the following properties after heat treatment:
- (a) a half width (2θ) of a diffraction peak (10×) (38° to 49°) by X-ray diffraction is 4.2° or less, wherein 10× means a pseudo peak observed in the vicinity of the 101 plane graphite, and
