High-rate and long-life VS2 cathodes for hybrid magnesium-based battery

Novel safe hybrid Mg2+/Li+batteries have been fabricated using Mg anode, VS2-GO cathode and APC-LiCl dual salt electrolyte. The highly stable framework and graphene wrapped structure of VS2-GO provide more active sites, larger electrode-electrolyte contact area, rapid ion diffusion and electron transport, leading to high-rate capability and cycling stability. The excellent performance stands out among the previous hybrid Mg2+/Li+ battery systems in coin cells.308
