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

Green Car Congress

Theoretical calculations demonstrate that the curved surfaces bind lithium with a stronger affinity than the planar surface with zero curvature, particularly the structure with a positive curvature, making it possible to accomplish the high capacity of the carbon anode in an extremely cold environment. —Lu et al.

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

Green Car Congress

But the cars and SUVs used in these situations drive more miles each year than a typical personal vehicle, contributing a higher proportion of greenhouse gases to the environment. In the simulations, battery-powered vehicles, particularly the 40 kWh ones, needed more frequent and longer trips without passengers to get to recharging stations.
