University of Texas researchers and Seoul National University have designed a new manganese and sodium ion based material that might replace many lithium ion batteries. The new chemistry offers a potentially lower-cost, more eco-friendly option to energize next generation devices and electric cars. In the battle of the batteries, lithium-ion technology is the reigning champion, […]

Closing In On The Lithium-Sulfur Battery
May 10, 2017 | Leave a Comment
Materials researchers at the Paul Scherrer Institute PSI in Switzerland collaborating with the Université Grenoble Alpes (France), have developed a method that could enable a breakthrough for the lithium-sulfur battery. This could be very useful because: In theory, lithium-sulfur batteries can deliver considerably more energy than today’s conventional lithium-ion batteries, but current prototypes show a […]

Researchers at the U.S. Naval Research Laboratory’s (NRL) Chemistry Division have developed a safer nickel zinc battery chemistry to replace fire-prone lithium-ion batteries. Joseph Parker, Jeffrey Long, and Debra Rolison from NRL’s Advanced Electrochemical Materials group are leading an effort to create an entire family of safer, water-based, zinc batteries. They have demonstrated a breakthrough […]

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 […]

Pacific Northwest National Laboratory research shows adding a pinch of chemical additive to a lithium-metal battery’s electrolyte helps make rechargeable batteries that are stable, charge quickly, and go longer in between charges than lithium-ion batteries. New, early-stage research shows adding a small amount of the chemical lithium hexafluorophosphate to a dual-salt, carbonate solvent-based electrolyte can […]
