Suppressing H2 evolution by using a hydrogel for reversible Na storage in Na3V2(PO4)3
TL;DR: In this article, the authors reported a low-cost hydrogel electrolyte by adding 3 wt% poly(acrylate sodium) (PAAS) into 1 M Na2SO4 aqueous electrolyte, which achieves a widened electrochemical stability window (ESW) of 2.45 V on stainless steel current collector from 2.12 V in 1 M N 2SO4 anode material, and the H2 evolution potential reached −1.75 V vs. Ag/AgCl on titanium current collector.

Challenges for Rechargeable Li Batteries
John B. Goodenough,Youngsik Kim +1 more
TL;DR: In this paper, the authors reviewed the challenges for further development of Li rechargeable batteries for electric vehicles and proposed a nonflammable electrolyte with either a larger window between its lowest unoccupied molecular orbital and highest occupied molecular orbital (HOMO) or a constituent that can develop rapidly a solid/ electrolyte-interface (SEI) layer to prevent plating of Li on a carbon anode during a fast charge of the battery.
