One of the inventors of the lithium-ion battery used by laptops, phones, and tablets has announced the next generation of battery technology: a solid-state battery that offers three times the energy density of today’s batteries and is safer to boot.
John Goodenough, the Fermi award winner who identified the lithium cobalt oxide material that forms the cathode used in today’s Li-ion batteries, teamed up with Maria Helena Braga to develop a battery that uses solid glass as an electrolyte. (It’s not the first solid-state battery, however; Samsung and MIT collaborated on a competing solid-state battery technology last year.)
