Hydronium-ion batteries show promise for sustainable high-power energy storage, according to scientists at Oregon State University, which claims to have developed the world’s first battery to use only hydronium (H3O+) ions as the charge carrier. The hydronium ions are reversibly stored in an electrode made from the organic crystalline solid perylenetetracarboxylic dianhydridem (PTCDA). Dilute sulphuric acid is the electrolyte. ...
