High-Performance Organic Lithium Batteries with an Ether-Based Electrolyte and 9,10-Anthraquinone (AQ)/CMK-3 Cathode.

ABSTRACT: Organic carbonyl electrode materials of lithium batteries have shown multifunctional molecule design and high capacity, but have the problems of poor cycling and low rate performance due to their high solubility in traditional carbonate-based electrolytes and low conductivity. High-performance organic lithium batteries with modified ether-based electrolyte (2 m LiN(CF₃SO₂)₂ in 1,3-dioxolane/dimethoxyethane solvent with 1% LiNO₃ additive (2m-DD-1%L)) and 9,10-anthraquinone (AQ)/CMK-3 (AQC) nanocomposite cathode are reported here. The electrochemical results manifest that 2m-DD-1%L electrolyte promotes the cycling performance due to the restraint of AQ dissolution in ether-based electrolyte with high Li salt concentration and formation of a protect
