University of Delaware researchers have demonstrated a new polysulfide entrapping strategy that greatly improves the cycle stability of Lithium Sulfide batteries. This may be significant as the energy density of lithium-sulfur (Li-S) batteries is five times higher than that of Lithium-Ion (Li-ion) batteries. Rechargeable Li-ion batteries are the power behind most modern portable electronics. But […]

Researchers at Hanyang University, and their U.S. and Qatar colleagues combined two complementary carbon materials to boost the lithium ion cathode electrode’s conductivity. The team of researchers has designed a cathode for such batteries that holds up to 10 times as much sulfur as other designs without a drop in performance. A test battery made […]

Stanford University scientists have created a new carbon material that significantly improves the performance of batteries and supercapacitors. Zhenan Bao, the senior author of the study and a professor of chemical engineering at Stanford said, “We have developed a ‘designer carbon’ that is both versatile and controllable. Our study shows that this material has exceptional […]
