Diffusionless charge transfer

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.
