Monolithically integrated GaN half bridge enables smaller, more powerful voltage converters

Germany’s Fraunhofer Institute for Applied Solid State Physics has demonstrated what it calls the world’s first monolithically integrated GaN half bridge for the 600 volt class. Half bridge circuits are the centerpiece of many voltage converters.
Monolithic integration combines several components on a single GaN chip, enabling small, powerful systems to …read more

Adding quartz powder to Li-S battery electrolyte slows capacity loss

Researchers at the Paul Scherrer Institute (PSI) in Switzerland and the Université Grenoble Alpes in France have developed a simple method that they say can improve the performance of lithium-sulfur batteries by 25-30%.
In “Direct observation of lithium polysulfides in lithium-sulfur batteries using operando X-ray diffraction,” published in Nature Energy, Joanna …read more
