Proton batteries are an innovative and environmentally friendly type of battery in which charge is carried by protons, which are positively charged hydrogen ions. A team of researchers has now developed organic sulfonamides as a robust and flexible material for cathodes in these batteries. As the team explain in the journal Angewandte Chemie International Edition, sulfonamide cathodes also achieve a higher output voltage than conventional cathodes.
