As part of the study, the team took NMR scans of silicon anodes as the battery cycled, watching how lithium atoms acted once inside. The cells were then left idle for seven months.

But first, the researchers had to set up control experiments, which involved scans of phosphate ions in the absence of calcium via nuclear magnetic resonance (NMR) spectroscopy and cryogenic ...
