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

Green Car Congress

Scientists at Friedrich Schiller University in Jena, together with colleagues from Boston University (BU) and Wayne State University (WSU), have now succeeded in preventing dendrite formation and thus at least doubling the lifetime of a lithium metal battery. Here, the use of an ultrathin (?1.2 —Rajendran et al.

Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Overall, electrification reduces net external costs to society by 3–11% (5–24¢ per trip), depending on the assumed social cost of carbon. —Mohan et al. Mohan et al.

Drexel team develops stable Li-S battery with carbonate electrolyte

Green Car Congress

Researchers at Drexel University have stabilized a rare monoclinic ?-sulfur sulfur phase within carbon nanofibers that enables successful operation of Lithium-Sulfur (Li-S) batteries in carbonate electrolyte for 4000 cycles. AN open-access paper on their work is published in Communications Chemistry. —Pai et al.
