PSI, Switzerland and Université Grenoble Alpes (France) researchers have developed a method that could enable a breakthrough for the lithium-sulphur battery. In theory, these batteries can deliver considerably more energy than today’s conventional lithium-ion batteries, but current prototypes show a distinct loss of capacity after just a few charging cycles. So they are not yet fit for widespread use, for instance in electric vehicles. With their new method, the researchers were able to gain crucial insights into how the rapid capacity loss occurs...
