This work studied hybrid batteries assembled with a Mg metal anode, a Li(+) ion intercalation cathode and a dual-salt electrolyte containing Mg(2+) and Li(+) ions. We show that such hybrid batteries were able to combine the advantages of Li and Mg electrochemistry. They delivered outstanding rate performance (83% capacity retention at 15 C) with superior safety and stability (~5% fade for 3000 cycles).
这项工作研究了由镁金属阳极、锂离子嵌入阴极以及含有镁离子和锂离子的双盐电解质组装而成的混合电池。我们表明，这种混合电池能够结合锂和镁电化学的优点。它们展现出出色的倍率性能（在15℃下容量保持率为83%），同时具有卓越的安全性和稳定性（3000次循环后容量衰减约5%）。
