The majority of the world’s rechargeable batteries are now made using lithium-ion. Most rely on a combination of different rare earth metals such as cobalt or nickel for their electrodes. But around the world, teams of researchers are looking for alternative – and more sustainable – materials to build the batteries of the future.
In this episode, we speak to four battery experts who are testing a variety of potential battery materials about the promises they may offer.
Featuring Laurence Hardwick from the University of Liverpool, Robert Armstrong from the University of St Andrew's, Ulugbek Azimov from Northumbria University and Bill Yen from Stanford University.
Applications are now open for early career researchers to submit their projects for the Prototypes for Humanity 2025 awards and showcase in Dubai.
