US Army researchers developed New ‘WaterBattery’ for ‘On-The-Go’ Energy Storage.
The announcement was made on Science Direct. The researchers:
In summary, we successfully resolved the “cathodic challenge” of aqueous electrolytes by designing a unique inhomogeneous electrolyte additive approach to minimize competitive water reduction on graphite or Li-metal surfaces during the interphase formation.
Upon reductive decomposition during the first charging process, the highly fluorinated additive forms a protective interphase that enables the reversible cycling of both graphite and Li-metal anodes in aqueous electrolytes.
