Title: Electrolyte for stable cycling of rechargeable alkali metal and alkali ion batteries

Abstract

Localized superconcentrated electrolytes (LSEs) and electrochemical devices including the LSEs are disclosed. The LSE includes an active salt, a solvent in which the active salt is soluble, and a diluent in which the active salt is insoluble or poorly soluble, wherein the diluent includes a fluorinated orthoformate.
