The synthesis and performance of new anode materials for aqueous batteries is described. These materials combine robust metal oxide electrode materials with organic materials based on anthraquinone (AQ) to vastly improve the energy and power densities and inhibit water splitting reactions. These amorphous materials are stable in aqueous electrolytes over a wide pH range, conductive, and can store as many as seven electrons per molecule. The organometallic anodes are currently being tested with nickel-oxide cathodes in alkaline conditions, lead-oxide cathodes in acidic conditions, and manganese-oxide cathodes in pH-neutral conditions, and show promise in producing a next-generation battery anode material for residential and commercial as well as grid-scale energy storage.
