WebMay 13, 2024 · Multi-electron redox is considerably crucial for the development of high-energy-density cathodes. Here we present high-performance aqueous zinc-manganese batteries with reversible Mn 2+ /Mn 4+ double redox. The active Mn 4+ is generated in situ from the Mn 2+ -containing MnO x nanoparticles and electrolyte. WebFluorographene (or perfluorographane, graphene fluoride) is a fluorocarbon derivative of graphene.
