This article comes from the Argonne National Laboratory. A team of academic researchers is seeking clarity on predictive plug-in electric vehicle (PEV) models. An examination of more than three dozen studies is providing some meaningful insights. “The value of the models is not in their predictive power, but in connecting ‘important’ factors in a way that…
Argonne National Lab scientists see promise in Lithium-air battery
The key features of the team’s newly developed battery cell are a new protective coating for the lithium metal anode, which prevents the anode from reacting with oxygen and hence deteriorating, and a novel electrolyte mixture that allows the cell to operate in an air atmosphere.
The wet road to fast and stable batteries
The battery research team tracked how material composition and structure changed when heated by using various advanced characterization techniques, including x-ray diffraction provided by the Advanced Photon Source
Update on what causes micro cracks that eventually fail turbine bearings
What initiates these tiny cracks that eventually cause turbine shutdowns is still something of a mystery, but it is slowly giving way with close scrutiny.
NREL’s Gearbox Collaborative provides more insight why gearboxes fail – and a solution
It’s not often that a technical conference leaves attendees with an ah-ha moment, but it happened at the recent Gearbox Reliability Collaborative sponsored by NREL at its offices in Golden, Colo. All presentations were good, but three in particular answered interesting questions raised by those preceding. An early presentation by Aaron Greco from the Tribology…
