Energy storage is slowly shifting utility planning practices from the current paradigm, which ensures grid reliability by building reserve generation resources, to ensuring grid reliability by optimizing grid services.
PNNL researchers demonstrate how the excitation of oxygen atoms that contributes to better performance of a lithium-ion battery also triggers a process that leads to damage, explaining a phenomenon that has been a mystery to scientists.
PNNL’s Dan Gaspar and John Holladay were part of the Co-Optima leadership team honored by DOE’s Vehicle Technologies Office. The award recognized groundbreaking work to synergistically improve fuels and engines to maximize fuel economy.
Editors of the journal Emission Control Science and Technology deemed “Coating Distribution in a Commercial SCR Filter” Best Paper in 2018. The authors include PNNL's Mark Stewart, Carl Justin Kamp, Feng Gao, Yilin Wang, and Mark Engelhard.
Several years ago, a relatively new catalyst for vehicle emission control began showing failure. A team at PNNL found that this seemingly suicidal catalyst wasn’t actually self-destructing but was the victim of an external assailant.
A recent study pinpointed the reaction front where lithium (Li) dendrites can come into contact with cathode materials. It also detailed the Li propagation pathway and reaction steps that lead to cathode failure.
