The NMR spectroscopy technique was created and used in the ANL study to track the fate of lithium atoms in silicon-anode cells during their charging and discharging processes, followed by a seven ...

The new NMR methods are thus not limited to silicon-anode batteries. They can easily be applied to other emerging battery technologies like sodium-ion and solid-state.
