Visualizing a battery's lithium "whiskers" and their degrading effects
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.
A Leap in Using Silicon for Battery Anodes
Researchers at PNNL have come up with a novel way to use silicon as an energy storage ingredient, replacing the graphite in electrodes. Silicon can hold 10 times the electrical charge per gram, but it comes with problems of its own.
Redox Flow Battery Paper Makes Editor’s Choice
A paper published last year by scientists at Pacific Northwest National Laboratory was featured in the 2021 Editor’s Choice collection for the Cell Reports Physical Science journal.
Silicon Anodes Muscle in on Battery Technology
One effort toward better batteries for electric vehicles is hitting overdrive, thanks to new findings about the desirable silicon anode.
