New paper published in ACS Applied Energy Materials on quaternary electrolyte design for superior supercapacitors

New paper published in ACS Applied Energy Materials on the use of quaternary electrolytes for enhanced capacitive energy storage. This collaborative work explores quaternary electrolytes (two distinct cations and two distinct anions) as a practical strategy to improve electrical double-layer capacitors – combining a solvable theoretical pore-charging framework with experimental validation using [EMIM][BF₄] mixed with lithium salts. We show that quaternary mixtures can outperform neat ionic liquids and conventional mixtures sharing a common ion, enabling more balanced charge storage in nanoporous electrodes and enhanced capacitive energy storage.
