PhD Description:

Gas evolution is one of the most important causes of battery degradation, and a potential trigger of battery unsafe behaviour, since gas accumulation will deform the battery chasing, build a high internal pressure and potentially short the electrodes inside the battery producing high local temperatures that can cause uncontrolled thermal runaway. Gases trapped within the composite electrodes locally isolate part of the active material, and as a result, the rest of the electrode is forced to work under more stressed conditions, which in turn triggers more degradation reactions concomitant with more gas evolution.Very small amount of gases can produce catastrophic events. This studentship will contribute towards the development of a highly sensitive, mass spectrometry based techniques to detected gases during the operation of lithium batteries.

The studentship is funded by the Faraday Institution program ( https://faraday.ac.uk/ ) to train future generations of UK scientists to work in electrochemical storage, and the participants will receive a comprehensive, state-of-the-art training to enhance their research pursuits ( https://faraday.ac.uk/research/phd-studentships/ ).

The work will be carried out as part of the Faraday Institution project on battery degradation ( https://faraday.ac.uk/extending-battery-life/ ), a large consortium involving 9 universities and 25 investigators, led by Prof. Clare Grey. The work to be carried out at Southampton will focus on the analysis of gas evolution, building on our previous experience on the fundamental characterization of battery reactions (see, for example, J. Am. Chem. Soc., 2018, 140, pp 1428-1437).

The project is funded for 4 years and welcomes applicants from the UK/EU who have or expect to obtain a first or upper second class degree in chemistry or allied subjects/relevant disciplines. Funding will cover fees and an enhanced stipend.

Due to funding restrictions this position is only open to UK/EU applicants
