摘要
A rechargeable hybrid Mg2+/Li+ battery is designed by coupling a dendrite-free magnesium anode with an electrolyte-compatible cathode in a mixed Mg2+/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. © 2014 WILEY-VCH Verlag GmbH & Co.
