ABSTRACT:
In a method of manufacturing a porous coke suitable as a charge-storing material in electrochemical capacitors, one manufactures or provides a non-calcined isotropic coke with spherical or onion-shaped morphology and low graphitizability as a starting material. The starting material is comingled with a caustic alkali to obtain a homogenous mixture. The homogenous mixture is heat treated at a temperature in a range between 650 and 950° C. to obtain the porous coke. The porous coke is washed and neutralized.
