Electrolyte for high efficiency cycling of sodium metal and rechargeable sodium-based batteries comprising the electrolyte

Year: 2023
Type: article
Abstract: Embodiments of a non-aqueous electrolyte for a rechargeable sodium (Na)-based battery comprise a sodium salt and a nonaqueous solvent, the electrolyte having a sodium salt concentration .gtoreq.2.5 M or a solvent-sodium salt mole ratio .ltoreq.4:1. Na-based rechargeable batteries including the electrolyte exhibit both high cycling stability and high coulombic efficiency (CE). Some embodiments of the disclosed batteries attain a CE.gtoreq.80% within 10-30 charge-discharge cycles and maintain a CE.gtoreq.80% for at least 100 charge-discharge cycles. In certain embodiments, the battery is an anode-free battery in the as-assembled initial state.
