Shown are a) the voltage profiles of Ti/Zn coin cell in the first 10 cycles; and (b) the corresponding columbic efficiency of zinc metal, both during the zinc-metal plating/stripping cycle under conditions specified in the paper’s supplementary information.

Chunsheng Wang, a UMD professor of chemical and biomolecular engineering and a corresponding author of the paper, notes that “existing zinc batteries are safe and relatively inexpensive to produce, but they aren't perfect due to poor cycle life and low energy density. We overcome these challenges by using a water-in-salt electrolyte.”https://www.toppersnotes.com/ies-gate-samples/
ARL fellow and team leader Dr. Kang Xu added that “the safety hazard of lithium-ion batteries are rooted in the highly flammable and toxic non-aqueous electrolytes used therein. The batteries of aqueous nature thus become attractive, if they can be made rechargeable with high energy densities. Zinc is a natural candidate.”
