Researchers use carbon-based anodes with “bumpy” surfaces for Li-ion batteries that last longer in extreme cold

Green Car Congress

The resulting 12-sided carbon nanospheres had “bumpy” surfaces that demonstrated excellent electrical charge transfer capabilities. The resulting 12-sided carbon nanospheres had bumpy surfaces that demonstrated excellent electrical charge transfer capabilities. An open-access paper on the work is published in ACS Central Science.

Carbon nanomembrane prevents dendrite formation in Li-metal batteries, doubles lifetime

Green Car Congress

The energy density of traditional lithium-ion batteries is approaching a saturation point that cannot meet the demands of the future—in electric vehicles, for example. Lithium metal batteries can provide double the energy per unit weight when compared to lithium-ion batteries. Here, the use of an ultrathin (?1.2

Japanese start-up seeks to commercialize dual-carbon battery technology; anion intercalation

Green Car Congress

Start-up Power Japan Plus announced plans to commercialize a dual-carbon battery technology, which it calls the Ryden dual carbon battery. Dual-carbon (also called dual-graphite) batteries were first introduced by McCullough and his colleagues at Dow Chemical in a 1989 patent, and were subsequently studied by Carlin et al.
