‘Flat water’ provides a battery boost
A popular approach for developing better batteries and other energy-storage devices is incorporating atoms-thick sheets of solid-state materials. This strategy may hold for liquids, too. Researchers have found that test devices using tungsten oxide electrodes have improved energy-storage kinetics when thin layers of water are confined between crystalline WO3 sheets (Chem. Mater. 2017, DOI: 10.1021/acs.chemmater.6b05485). Hydrated electrodes charge and discharge faster than . . .
