LLNL’s novel approach combines 2-color spectroscopy with CRDS, a combination not previously utilized.

There are prominent technical challenges arising from spinning a battery on the order of kilohertz as required by magic angle spinning in order to obtain spectral resolution that are addressed and enable operando solid-state NMR. The operando NMR measurement allows for continuous monitoring of the battery components and of potential metastable states that may exist during…

This technology is an extremely small and robust cell in which a very small volume of gas is sampled, while maintaining high sensitivity and specificity, by combining it with:

• Highly tunable and commercially available semiconductor lasers, such as edge emitting lasers and vertical cavity surface emitting lasers (to provide various absorption lines of one specie and to capture…
