Grab some lunch from the Darwin servery and enjoy an interesting science talk and discussion over lunch. Looking forward to seeing you there.

Electric vehicles are essential for future society, and are already a reality in our daily lives. The performance of their batteries, and improving their safety, limits our transition from fossil fuels. They are complicated black boxes, whose individual elements interact with one another throughout operation, making it challenging to unpick the factors affecting performance degradation. Raman Spectroscopy is a non-perturbing spectroscopic technique, which allows chemical species to be monitored throughout battery operation. A potential limitation of this technique is that optical access to the sample is required, which can be challenging. Optical fibres provide one solution, enabling in-situ and operando sensing of Li:ion batteries via embedded fibre-optic Raman sensors.
