We report a design of high voltage magnesium-lithium (Mg-Li) hybrid batteries through rational controls of the electrolyte chemistry, electrode materials and cell architectures. Prototype devices with LiFePO4 and LiMn2O4 cathodes exhibit voltages higher than 2.5 V (vs. Mg) and a high specific energy density of 246 Wh/kg under conditions that are amenable for practical applications. The successful demonstrations reported here could be a significant step forward for practical hybrid batteries.
