The advent of membrane-less zinc-anode aqueous batteries with lithium battery-like voltage
A 2.5 to 3.4 V Zn|MnO2 membrane-less solid-state battery accessing the 617 mA h g−1 theoretical capacity of MnO2 and its application in e-mobility is reported. This concept is made possible by a buffering layer that regulates the battery’s pH.
