The excessive formation of gases is also an important safety concern, since it can cause the cell’s rupture and explosion, with the consequent release of toxic vapors.

Unfortunately, the techniques currently available to study gas evolution from batteries are very limited.

But we have recently developed powerful operando gas analysis methods, including online mass spectrometry and operando pressure measurements (see, for example, J. Am. Chem. Soc., 2018, 140, pp 1428–1437), and we are currently applying these techniques to study state-of-the-art battery materials within the Faraday Institution project on battery degradation (https://faraday.ac.uk/extending-battery-life/).

You will apply these gas analysis methods to investigate the fundamental causes of battery degradation and to develop diagnostics and prevention approaches to achieve safe and long-lasting batteries, with special focus on the requirements for electric vehicle applications.
