Making Lithium Sulfur Batteries Last Longer
March 8, 2017 | Leave a Comment
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 […]

A New Flow Battery Chemistry
March 4, 2015 | 1 Comment
Pacific Northwest National Laboratory (PNNL) is announcing a new zinc-polyiodide redox flow battery that uses an electrolyte that has more than two times the energy density of the next-best flow battery and may exceed lithium-ion. The new zinc-polyiodide redox flow battery is described in the team’s paper published in Nature Communications. The zinc-polyiodide redox energy […]
