Rechargeable aqueous Zn-ion batteries are attractive cheap, safe and green energy storage technologies but bottlenecked by limitation in high-capacity cathode compatible electrolyte to achieve satisfactory cyclability. Here we report the application of nonstoichiometric ZnMn2O4/carbon composite as a new Zn-insertion material Zn(CF3SO3)2 electrolyte. In 3 M solution that enables ∼100% Zn plating/stripping efficiency with long-term stability suppresses Mn dissolution, spinel/carbon hybrid...
Controlling electrode growth Batteries with metal anodes can grow dendrites during cycling, which cause short circuits in a battery or subsequently reduce the charge capacity.
