Lithium–antimony–lead liquid metal battery for grid-level energy storage
All-liquid batteries comprising a lithium negative electrode and an antimony–lead positive electrode have a higher current density and a longer cycle life than conventional batteries, can be more easily used to make large-scale storage systems, and so potentially present a low-cost means of grid-level energy storage.

A metal-free organic–inorganic aqueous flow battery
Flow batteries, in which the electro-active components are held in fluid form external to the battery itself, are attractive as a potential means for regulating the output of intermittent renewable sources of electricity; an aqueous flow battery based on inexpensive commodity chemicals is now reported that also has the virtue of enabling further improvement of battery performance through organic chemical design.

A new anode material for oxygen evolution in molten oxide electrolysis
Molten oxide electrolysis is considered a promising route for extractive metallurgy with much reduced carbon dioxide emissions relative to traditional routes; now a new chromium-based alloy has been developed for use as an oxygen evolving anode that remains stable in the high-temperature corrosive conditions found during iron production via electrolysis.
