With World EV Day on the 9th of September, in this episode we’re looking at the power behind electric vehicles – the batteries themselves. As more of us consider ditching our petrol cars, in favour of ones we simply plug in, we’re going to explore both the positives and negatives – and the charges for-and- against this developing technology.

Jamie Foster is a Professor of Applied & Industrial Mathematics at the University of Portsmouth and in this wide-ranging episode, you’ll hear how batteries work, how sodium (salt) might be the replacement for the finite ingredients currently used, such as nickel and cadmium – and the steps that need to be taken to get us all comfortable with EVs when we next buy a car.

We’d love you to be part of the discussion, too. Email your questions on this episode or ideas for future episodes to
