Real-time tracking of the dynamic chemistry in commercial batteries by infrared fibre spectroscopy provides insight into the parasitic reactions that occur at the electrodes and in the electrolyte. This chemical-sensing method enables identification of chemical species and observation of Na(Li) inventory changes upon cycling, providing essential information for improving battery technology.
