Fast kinetics of multivalent intercalation chemistry enabled by solvated magnesium-ions into self-established metallic layered materials

Abstract

While magnesium rechargeable batteries could combine high energy density with low cost and good safety, the extremely sluggish reaction kinetics remains to be overcome. Here, the authors show that by using solvated Mg2+ intercalation, the high charge density of bare Mg2+ may be effectively mitigated.
