Outline of Final Research Achievements

Our research group already demonstrated electrochemical potassium intercalation into graphite electrode and we here studied application of the potassium intercalation to new potassium-ion capacitors. Especially we investigated different carbons, binders, and electrolyte solutions for the capacitors. As a result, we succeeded in the superior demonstration of negative electrode for potassium-ion capacitors to that lithium-ion capacitors.
