Two Mg-Li dual salt hybrid electrolytes are developed, which exhibit excellent oxidative stability up to around 3.8 V (vs. Mg/Mg(2+)) on an aluminum current collector, enabling the successful coupling of several state-of-the-art lithium-ion intercalation cathodes (LiMn2O4, LiCoO2 and LiNi1/3Mn1/3Co1/3O2) with magnesium metal anodes. The Mg-LiMn2O4 battery delivers an initial discharge capacity of about 106 mA h g(-1) with a working voltage of around 2.8 V (vs. Mg/Mg(2+)), highlighting the highest working voltage of rechargeable batteries with magnesium metal anodes to date.
开发了两种镁-锂双盐混合电解质，在铝集流体上，它们在高达约3.8 V（相对于Mg/Mg(2+)）时表现出优异的氧化稳定性，能够成功地将几种先进的锂离子插层阴极（LiMn2O4、LiCoO2和LiNi1/3Mn1/3Co1/3O2）与镁金属阳极耦合。镁-锂锰氧化物电池的初始放电容量约为106 mA h g(-1)，工作电压约为2.8 V（相对于Mg/Mg(2+)），这突出了迄今为止具有镁金属阳极的可充电电池的最高工作电压。
