摘要
Aqueous Zinc-ion Batteries
In article number 2200654, Linfeng Hu and co-workers develop NASICON-typed V-Mn transition metal phosphate, Na4VMn(PO4)3, as a cathode material for robust aqueous Zn-ion storage. Taking advantage of its high-voltage properties that originate from the inductive effect and two-step electron transfer mechanism between V4+/V3+ and Mn3+/Mn2+ redox couple, the Na4VMn(PO4)3 cathode exhibits excellent overall battery performance with an energy density of 309.7 Wh kg−1, and good rate capacity and cycling stability (89.1% capacity retention after 3000 cycles).
