Scientists have uncovered a root cause of the growth of needle-like structures—known as dendrites and whiskers—that plague lithium batteries, sometimes causing a short circuit, failure, or even a fire.

PNNL researchers have created a chemical cocktail that could help electric cars power their way through extreme temperatures where current lithium-ion batteries don’t operate as efficiently as needed.

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.

Jaehun Chun spoke at a National Academies of Sciences, Engineering, and Medicine open data-gathering session on separation science.

Fifteen PNNL scientists are part of a team that has identified a set of biomarkers that indicate which patients infected with the Ebola virus are most at risk of dying from the disease.

The Multi-omics for Microbiomes conference focused on different approaches that let researchers paint better pictures of microbial communities.

As a Department of Energy national laboratory, you would expect Pacific Northwest National Laboratory to perform research in chemistry, physics and engineering in support of our energy, environmental and security missions.
