Electrochemical-Conditioning-Free and Water-Resistant Hybrid AlCl /MgCl /Mg(TFSI) Electrolytes for Rechargeable Magnesium Batteries.

Rechargeable magnesium batteries are a promising alternative to Li-based energy storage because of their abundant and inexpensive components. The high sensitivity and reactivity of the organic Mg electrolyte makes their development challenging. Herein, we develop a new hybrid electrolyte, based on three simple inorganic salts of MgCl , AlCl , and Mg(TFSI) .
