DOI: 10.1002/adma.202202380
Abstract: Electrochemical capacitors (ECs), including electrical‐double‐layer capacitors and pseudocapacitors, feature high power densities but low energy densities. To improve the energy densities of ECs, redox electrolyte‐enhanced ECs (R‐ECs) or supercapbatteries are designed through employing confined soluble… read more here.
