               1. A method for preparation of an asymmetric supercapacitor comprising: 
            forming a polyaniline (PANI) nanowire on a carbon cloth (CC) substrate (PANI/CC) by polymerization of aniline; 
                depositing cobalt-nickel layer double hydroxide (CoNi-LDH) on the PANI/CC by a hydrothermal process; and 
                calcining the cobalt-nickel layer double hydro hydroxide (CoNi-LDH) in the PANI/CC at 800° C. to form a metal carbide (CoC@NiC) on the carbon cloth.
