    An aluminium-ion battery is reported that can charge within one minute, and offers improved cycle life compared to previous devices; it operates through the electrochemical deposition and dissolution of aluminium at the anode, and the intercalation/de-intercalation of chloroaluminate anions into a novel graphitic-foam cathode.

    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.

    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.

    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.

    An inorganic semiconductor can take the place of the liquid electrolyte typically used in dye-sensitized solar cells. This achievement points the way to making these devices more easily manufactured and more stable. See Letter p.486
