Swedish researchers at Linköping Universitet have increased the capacity of graphene to store an electrical charge by introducing defects into the perfect surface of graphene on silicon carbide. The result increases our knowledge of how this ultrathin material can be used. The team’s research paper and results have been published in the scientific journal Electrochimica […]






Helmholtz-Zentrum Berlin für Materialien und Energie scientists have fabricated a nanomaterial made from nanoparticles of a titanium oxide compound for lithium sulfur battery cathodes. The titanium oxide, Ti4O7 is characterized by an extremely large surface area, and was tested as a cathode material in lithium sulfur batteries. Presently lithium batteries are one of the best […]






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 […]






An Argonne National Laboratory team of researchers has identified one of the major culprits in capacity fade of high-energy lithium-ion batteries. Scientists refer to a battery becoming old is its diminished performance as “capacity fade,” as the amount of charge a battery can supply decreases with repeated use. Capacity fade is the reason why a […]
