    In contrast to lithium-ion batteries where lithium ions carry the charge, a proton battery, making use of a hydrated Prussian blue analogue electrode, is shown to be able to transmit charges in the fashion of the Grotthuss mechanism, displaying ultrafast-rate and ultralong-life properties.

    Aluminium−graphite batteries can reversibly store AlCl4 ions at their cathodes, but the large consumption of electrolytes reduces their specific energy. Here a cathode based on redox-active triangular organic molecules is shown to be able to take up AlCl2+, offering hope towards complete Al-ion storage.
