cheap, and extendable biomaterial precursor. It has showed significant SSA of

tions, and this is better than traditional biomass-originated active carbon products. In 1 M H2SO4, supercapacitors based on porous carbon (from frozen tofu) revealed 243 F g−1 specific capacitance, and in BMIMBF4/AN, it showed an extraordinary power density of about 72 W h kg−1 at an ordinary 889 W kg−1 energy density. Such carbonization procedure offers a potentially helpful strategy from abundant supportable resources to design carbon electrode materials with supreme execution for

In synopsis, this chapter has explained how KOH activation has been utilized to convert C60 molecules to a 3D carbon, while at the same time, doping with pyridinic and pyrrolic nitrogen has huge impact in energy storage capacity. Meanwhile, a graded porous carbon was obtained through sponge KOH activation via GO loading. Further, physical properties such as low sheet obstruction, high BET surface, and higher conductivities are accomplished based on the carbon activation through KOH, which introduces sort of nitrogen which covers defects from graphitic lattice eventually. Every one of these benefits leads to the great electrochemical execution of carbon terminals. Further, carbonization procedure offers a potentially helpful strategy from abundant supportable resources to design carbon electrode materials
