Salt–solvent synchro-constructed robust electrolyte–electrode interphase for high-voltage lithium metal batteries

A simple electrolyte formula of “single salt single solvent” —1 M LiDFOB in ES—enables the stable operation of an NCM622|Li full cell (2.5 mA h cm −2 , N/P = 4) under harsh conditions of high voltage (4.6 V) and wide temperature range (−30 to 60 °C).
