Abstract

Abstract : Two Mg–Li dual salt hybrid electrolytes are developed, which exhibit excellent oxidative stability up to around 3.8 V ( vs. Mg/Mg 2+ ) on Al, and were successfully applied in hybrid Mg–Li cells with lithium-ion intercalation cathodes and magnesium metal anodes. Abstract : Two Mg–Li dual salt hybrid electrolytes are developed, which exhibit excellent oxidative stability up to around 3.8 V ( vs. Mg/Mg 2+ ) on an aluminum current collector, enabling the successful coupling of several state-of-the-art lithium-ion intercalation cathodes (LiMn2 O4, LiCoO2 and LiNi1/3 Mn1/3 Co1/3 O2 ) with magnesium metal anodes. The Mg-LiMn2 O4 battery delivers an initial discharge capacity of about 106 mA h g −1 with a working voltage of around 2.8 V ( vs. Mg/Mg 2+ ), highlighting the highest working voltage of rechargeable batteries with magnesium metal anodes to date.
