A rechargeable hybrid Mg 2+ /Li + battery is designed by coupling a dendrite‐free magnesium anode with an electrolyte‐compatible cathode in a mixed Mg 2+ /Li + electrolyte. Due to the highly reversible lithiation/delithiation of the cathode and Mg deposition/dissolution in the electrolyte, the battery demonstrates the best overall performance among reported magnesium‐ion batteries and mixed‐ion batteries in terms of cycling stability, specific capacity, specific energy, and rate capability.
