A green and cost-effective rechargeable battery with high energy density based on a deep eutectic catholyte†
Abstract
Deep eutectic systems with self-contained electroactive species have been recognized in this work as a distinct class of low-cost greener catholytes or anolytes that potentially have high concentration of electroactive species, hence high volumetric capacities. The viability of the concept was demonstrated by applying a new deep eutectic catholyte (DEC) in a proof-of-concept Li-DEC battery.
