Researchers at Georgia Tech backed by the U.S. Army Research Laboratory have developed a promising new cathode and electrolyte system that replaces expensive metals and traditional liquid electrolyte with lower cost transition metal fluorides and a solid polymer electrolyte. This opens a potential for less expensive, lighter and safer batteries that are a vital need […]

Massachusetts Institute of Technology researchers have found a new way to make cathodes for lithium batteries, offering improvements in the amount of power for both a given weight and a given volume. Researchers around the globe have been on a quest for batteries that pack a punch but are smaller and lighter than today’s versions, […]

University of Warwick, WMG, researchers have developed a new direct, precise internal temperature test of lithium-ion batteries. They investigated internal temperatures and the electrodes potentials and found that the batteries can be safely charged up to five times faster than the current recommended charging limits. The new technology works in-situ during a battery’s normal operation […]

Rice University scientists are using defects for high performance lithium ion batteries while Berkeley Lab scientists can make up disordered materials for better lithium ion cathodes. Rice materials scientist Ming Tang and chemists Song Jin at the University of Wisconsin-Madison and Linsen Li at Wisconsin and the Massachusetts Institute of Technology led a study that […]

Researchers at the University of Maryland and the U.S. Army Research Laboratory have developed a lithium-ion battery that uses a water-salt solution as its electrolyte. The chemistry solution also reaches the 4.0 volt mark desired for household electronics, such as laptop computers, without the fire and explosive risks associated with some commercially available non-aqueous lithium-ion […]
