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…)

UD researchers manipulate cubic zirconia to improve conductivity in fuel cells

Cubic zirconia has long been favored for its use in costume jewelry.

Known scientifically as yttria-stabilized zirconia, it is also a known conductor of oxygen, making it useful as an electrolyte in solid oxide fuel cells.

Researchers at the University of Delaware recently fabricated the material into very thin films on the surface of sapphire crystals using a technique called sputtering to determine whether the conductivity for oxygen could be improved, enabling solid oxide fuel cells to become a more economical and efficient electrical power source.

A North Carolina State University invention has significant potential to improve the efficiency of solar cells and other technologies that derive energy from light.

Dr. Ahmed El-Shafei’s research group invented a new “sensitizer,” or dye, that harvests more ambient and solar light than any dyes currently on the market for use in dye-sensitized solar cells (DSSCs). (more…)
