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

Green Car Congress

Then the team tested the material’s electrical performance as the anode, with lithium metal as the cathode, inside a coin-shaped battery. (a) In comparison, lithium-ion batteries made with other carbon-based anodes, including graphite and carbon nanotubes, held almost no charge at freezing temperatures. C and maintained 85.9%

NREL report finds electrified heavy-duty vehicle powertrains could provide lower total cost of ownership than diesel under certain conditions

Green Car Congress

A new total cost of ownership (TCO) study from the National Renewable Energy Laboratory (NREL) finds that battery-electric and fuel-cell electric commercial trucks could be economically competitive with conventional diesel trucks by 2025 in some operating scenarios. —Chad Hunter, lead author of the report and former NREL researcher.

UT Austin team achieves best reported full-cell hybrid Li-air battery cycling with new ordered catalyst

Green Car Congress

Cycling performance of the hybrid Li− air batteries with (top) ordered Pd 3 Fe/C air electrode and (bottom) conventional Pt/C air electrode. However, the cycle life of such hybrid systems is limited. Ordered intermetallic catalysts also appear to possess different catalytic properties in comparison to their disordered alloys.
