High energy capacitors boosted by both catholyte and anolyte

摘要

An electrical double layer capacitor (EDLC) energy storage device is provided that includes an electrolyte having an anionic catholyte and a cationic anolyte, a positively charged electrode, and a negative charged electrode, where negatively charged oxidized species in the anionic catholyte are electrostatically attracted to the positively charged electrode, where positively charged reduced species in the cationic anolyte are electrostatically attracted to the negatively charged electrode, where self-discharge of the EDLC energy storage device is prevented.
