Boosting a practical lithium carbon dioxide battery through a decoupled electrolyte.

ABSTRACT: Highly conductive electrolytes and stable electrolyte|electrode interfaces are desired for next-generation batteries. Constructing solid-electrolyte interphases on electrodes is a prevailing strategy for enhancing interfacial stability but fails to prevent inevitable breakdown and reformation of interphases during prolonged cycling. Herein, a decoupled electrolyte is designed by introducing a co-solvent (tetraethylene glycol dimethyl ether) with high stability and high positive electrostatic potential values into highly conductive dimethylformamide-based electrolytes, which suffer from electrolyte|positive electrode instability. The preferential adsorption of cations solvated with co-solvents on the positive electrode during discharge induces the formation of a co-solvent-rich localized en
