Claim 7:
8. The split cell supercapacitor of claim 1, wherein the at least one molybdenum doped carbon material is made by a method comprising:
heating a carbon material to at least 450° C. for 10 minutes to an hour to form a cracked carbon material;
wherein the carbon material is carbon nanotubes or graphene;
sonicating the cracked carbon material in water for at least 5 minutes to form a dispersion;
adjusting the pH of the dispersion to 1.5-3 with an acid to form a suspension;
mixing MoO42− molybdate ion into the suspension and stirring for at least 48 hours at 20-25° C. to form a solution;
filtering, washing with water, and drying the solution at a temperature of at least 70° C. for at least 3 hours, to form the at least one molybdenum doped carbon material.
