Big Leap Forward For Lithium Sulfur Cell Batteries
January 24, 2018 | 2 Comments
Lawrence Berkeley National Laboratory researchers have reported that a new lithium-sulfur battery component allows a doubling in capacity compared to a conventional lithium-sulfur battery, even after more than 100 charge cycles. Lithium-sulfur batteries are promising candidates for replacing today’s common lithium-ion batteries in electronics and electric vehicles since they are cheaper, weigh less, and can […]

A Big Step Forward for Lithium Sulfur Batteries
June 14, 2017 | Leave a Comment
Berkeley National Laboratory scientists have made a surprising discovery that could fix lithium-sulfur battery capacity fading. But for the capacity fading, lithium-sulfur batteries have great potential as a low-cost, high-energy, energy storage medium for both vehicle and grid applications. Gao Liu the corresponding author of the paper research paper said, “There’s a lot of demand […]

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 […]

Big Improvement to Lithium Ion Batteries Gets Closer
June 28, 2016 | Leave a Comment
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 […]
