Rice University scientists have found a touch of asphalt may be the secret to high-capacity lithium batteries that charge up to 20 times faster than commercial lithium-ion batteries. Chemist James Tour’s lab at Rice University developed anodes comprising porous carbon made from asphalt that showed exceptional stability after more than 500 charge-discharge cycles. A high-current […]

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, […]

Materials researchers at the Paul Scherrer Institute PSI in Switzerland collaborating with the Universit√© 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 […]

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 […]
