We have fabricated core-shell type hybridized micro particles composed of mesoporous manganese oxide and fullerene C₆₀ nanocrystals for capacitor electrode. However, we could not obtain high energy density due to the Stokes radius of electrolyte in this system.
In this paper, we focused on electrolytic solution, and investegated supporting electrolytes and pH of electrolytic solution for the problem.
As a result, using Rb₂SO₄ which has the smallest Stokes radius combination, we have successfully improved three times larger energy density.
