Abstract
The present invention relates to a carbonaceous material which is derived from a plant, having a specific surface area of 1800 to 3000 m2/g as measured by a BET method, a hydrogen element content of 0.42% by mass or less and an oxygen element content of 1.5% by mass or less.
Claims7
A carbonaceous material, having a specific surface area of 1800 to 3000 m2/g as measured by a BET method,
- a hydrogen element content of 0.05% by mass or more and 0.42% by mass or less;
- and
- an oxygen element content of 0.1% by mass or more and 1.5% by mass or less,
- wherein the carbonaceous material is derived from a plant and a degree of crystallinity as measured by the ratio ID/IG is from 1.2 to 1.5, wherein ID is the intensity of the D band and IG is the intensity of the G band in the Raman spectrum of the carbonaceous material.
