Sustainable cycling enabled by a high-concentration electrolyte for lithium-organic batteries†
Abstract
A high-concentration electrolyte is proposed to improve the reversibility and cycling stability of the cuprous tetracyano-quinodimethane (CuTCNQ) cathode. Free solvent molecules are greatly reduced and the dissolution of active organic species is suppressed. Additionally, an effective SEI layer is formed on the Li metal surface that prevents the reduction of dissolved Cu2+ ions.
