1. A supercapacitor electrode material comprising:
a carbon material comprising a carbon lattice structure; and
phosphorus (P) and boron (B) doped on the carbon material,
wherein the phosphorus atom is contained in an amount of 0.01 atomic % to 10 atomic %,
the boron atom is contained in an amount of 0.01 atomic % to 10 atomic %,
phosphorus and boron have a molar ratio in a range of 1:0.1 to 10, and
some carbons in the carbon lattice structure are replaced with phosphorus and boron to form PCO3 and BC3.
