1. The electrochemical degradation of an ionic liquid was investigated using a variety of carbon materials including carbon blacks, activated carbons, zeolite templated carbon, and mesoporous templated carbon. The carbon basal plane was found to be involved in the degradation reactions.
2. The structure of a mesoporous templated carbon was controlled to have different graphene stacking numbers and various amounts of nitrogen doping. It is found that the capacitance has a quantum origin and we successfully quantified the quantum capacitance for a full understanding of the origin of capacitance. Furthermore, the nitrogen-doped carbon shows enhanced quantum capacitance and a good overall performance in ionic liquid-based supercapacitors.
