The Nobel Foundation honored University of Texas engineering professor John Goodenough, 97, with the 2019 Nobel Prize in chemistry last fall.

Goodenough, along with researchers Michael Stanley Whittingham and Akira Yoshino, was recognized for contributions to the development of lithium-ion batteries, which power laptops, smartphones and other electronic devices. But those who work with Goodenough say he should be acknowledged not only for his scientific strides but also for his kindness. (more…)

New battery technology employs multifunctional materials

Lithium-ion batteries power a vast array of modern devices, from cell phones, laptops, and laser pointers to thermometers, hearing aids, and pacemakers. The electrodes in these batteries typically comprise three components: active materials, conductive additives, and binders. (more…)

Method developed at Berkeley Lab’s Advanced Light Source measures electronic changes in a working battery electrode

A new technique developed at Berkeley Lab’s Advanced Light Source could help scientists better understand and improve the materials required for high-performance lithium-ion batteries that power EVs and other applications.

The technique, which uses soft X-ray spectroscopy, measures something never seen before: the migration of ions and electrons in an integrated, operating battery electrode. (more…)

Study Reveals New Factor that could Limit the Life of Hybrid and Electric Car Batteries

COLUMBUS, Ohio – A new study of the batteries commonly used in hybrid and electric-only cars has revealed an unexpected factor that could limit the performance of batteries currently on the road.

Researchers led by Ohio State University engineers examined used car batteries and discovered that over time lithium accumulates beyond the battery electrodes – in the “current collector,” a sheet of copper which facilitates electron transfer between the electrodes and the car’s electrical system.
