New high-performance foldable cathode for Li-S batteries based on 3D activated carbon fiber matrix

Green Car Congress

A team at Sun Yat-sen University in China has developed new high-performance, stable cathode for Li-S batteries consisting of a 3D activated carbon fiber matrix (ACFC) and sulfur. For the composite cathodes with 3D conductive framework, however, the continuous carbon fibers act as high-speed electron pathway.

GWU team develops low-cost, high-yield one-pot synthesis of carbon nanofibers from atmospheric CO2

Green Car Congress

A team led by Dr. Stuart Licht at The George Washington University in Washington, DC has developed a low-cost, high-yield and scalable process for the electrolytic conversion of atmospheric CO 2 dissolved in molten carbonates into carbon nanofibers (CNFs.) Now, the team, which includes postdoctoral fellow Jiawen Ren, Ph.D.,
