Anomalous large capacitances of porous carbons based on protium adsorption

The capacitances of porous carbon anodes were determined using a Ni(OH)(2) cathode. We found that the capacitances were 300-700 F g(-1) and above 3 times those of the carbon anodes prepared by electrical double layer formation, revealing the large capacitances based on protium H adsorption in the presence of highly concentrated KOH solution.

Automated summary

The capacitances of porous carbon anodes were determined using a Ni(OH)(2) cathode. The capacitances were found to be 300-700 F g(-1), which is over 3 times higher than those of carbon anodes prepared by electrical double layer formation, indicating the larger capacitances achieved through protium H adsorption in the presence of highly concentrated KOH solution.
