What will batteries of the future be made of? Four scientists discuss the options – podcast

By Gemma Ware, Host, The Conversation Weekly Podcast, The Conversation

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 of The Conversation Weekly podcast, we speak to four scientists who are testing a variety of potential battery materials about the promises they may offer.
