Materials researchers at the Paul Scherrer Institute PSI in Switzerland collaborating with the Université Grenoble Alpes (France), have developed a method that could enable a breakthrough for the lithium-sulfur battery. This could be very useful because:
In theory, lithium-sulfur 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.
This means the technology isn’t ready for scaling to market such as in portable electronics or electric vehicles. With their new method, the researchers were able to gain crucial insights into how the rapid capacity loss occurs. And they showed: if quartz powder is added to the liquid component of the battery, this loss can be slowed down.
