Compared to magnesium metal batteries (MMBs) based on pure Mg2+ electrolyte, the MMBs based on hybrid electrolyte containing Mg2+ and Li+ possess some advantages such as long cycle life, fast charge and discharge processes, high Coulomb efficiency and more choices of cathode materials. The energy density of MMBs can be improved especially when conversion-based cathode materials are used. Recent development on dual-salt magnesium batteries based on conversion reaction or multiple electron transfer process was reviewed based on the aspects of sulfide and organic cathode materials. With the assistance of nano-structure regulation, conductive network construction, and ion pillaring, Mg-S and Mg-rhodizonate batteries are able to achieve a high energy density (i.e., 500 W·h/kg based on active cathode material) and a long-term cycle stability. This review proposed an additive salt strategy to accelerate the kinetics of MMBs based on conversion reaction, and provided some fresh insights for the future development of magnesium-based batteries.
