Electrochemistry

Electrochemistry is a discipline that deals with chemical reactions that involve an exchange of electric charges between two substances. Both chemical changes generating electric currents and chemical reactions triggered by the passage of electricity can be considered electrochemical reactions.

    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.
