High-voltage, super-stable sodium-zinc hybrid batteries

Researchers from the China University of Petroleum have synthesized a novel hydrogel electrolyte that, when paired with a Prussian blue cathode, achieves outstanding energy density and cyclability in sodium-zinc hybrid ion batteries. From ESS News Aqueous, non-lithium-based, rechargeable batteries are promising candidates for next-generation large-scale energy storage systems owing to their safety credentials and low cost. However, their commercialization is hindered by a narrow electrochemical stability window and relatively low energy density. With the development of advanced electrolytes a ...
