Mechanistic Investigation of a Hybrid Zn/V O Rechargeable Battery with a Binary Li /Zn Aqueous Electrolyte.

Low-cost, easily processable, and environmentally friendly rechargeable aqueous zinc batteries have great potential for large-scale energy storage, which justifies their receiving extensive attention in recent years. An original concept based on the use of a binary Li /Zn aqueous electrolyte is described herein for the case of the Zn/V O system. In this hybrid, the positive side involves mainly the Li insertion/deinsertion reaction of V O , whereas the negative electrode operates according to zinc dissolution-deposition cycles.
