NTSB Chair questions safety impact of heavy EVs

Green Car Congress

The US transportation sector accounts for the largest portion of US greenhouse gas emissions, and I firmly believe it is a human right to breathe clean air. They require more materials and energy to build and propel them, adding to emissions and energy use. We do have a climate crisis that needs to be addressed. —Shaffer et al.

UCSD, South 8 team report improved liquefied-gas electrolytes for Li-metal batteries

Green Car Congress

Improvements to a class of battery electrolyte first introduced in 2017—liquefied gas electrolytes—could pave the way to replacing the graphite anode with a lithium-metal anode. Meng and colleagues’ approach was to switch to a more compatible electrolyte, called liquefied gas electrolytes. —Yang et al.
