Popis: Zinc (Zn)-anode batteries, although safe and non-flammable, are precluded from promising applications because of their low voltage (2 V) and poor rechargeability. Here, we report the fabrication of rechargeable membrane-less Zn-anode batteries with high voltage properties (2.5 to 3.4 V) achieved through coupling cathodes and Zn-anodes in gelled concentrated acid and alkaline solutions separated by a gelled buffer interlayer containing the working ions. The concentrated gelled buffer interlayers perform dual functions of regulating the pH of the system and acting as the source and sink of the working ions. With this strategy we show low-cost membrane-less 2.5 to 3.4 V Zn-manganese dioxide (MnO
