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.

U Waterloo team shows four-electron conversion for Li-O2 batteries for high energy density; inorganic molten salt electrolyte, high temperature

Green Car Congress

The new work, published in Science , shows that four-electron conversion for lithium-oxygen electrochemistry is highly reversible. The Waterloo team is the first to achieve four-electron conversion, which doubles the electron storage of lithium-oxygen, also known as lithium-air, batteries. —Xia et al. —Linda Nazar.

Purdue team uses pollen grains as basis for carbon architectures for Li-ion anodes

Green Car Congress

A team at Purdue University has used pollens as the basis for carbon architectures for anodes in energy storage devices. One candidate is hard carbon which typically allows faster lithiation due to larger interlayer spacing, and higher cycling capacity than graphite due to the additional nanopore filling Li storage mechanism.
