Title: High Performance Batteries Based on Hybrid Magnesium and Lithium Chemistry

Magnesium and lithium (Mg/Li) hybrid batteries that combine Mg and Li electrochemistry, consisting of a Mg anode, a lithium-intercalation cathode and a dual-salt electrolyte with both Mg2+ and Li+ ions, were constructed and examined in this work. Our results show that hybrid (Mg/Li) batteries were able to combine the advantages of Li-ion and Mg batteries, and delivered outstanding rate performance (83% for capacities at 15C and 0.1C) and superior cyclic stability (~5% fade after 3000 cycles).
