SMU Solution May Be to Low-Cost, Long-Lasting Renewable Batteries for Electric Vehicles
Southern Methodist UniversityLithium-sulfur batteries have never lived up to their potential as the next generation of renewable batteries for electric vehicles and other devices. But SMU mechanical engineer Donghai Wang and his research team have found a way to make these Li-S batteries last longer – with higher energy levels – than existing renewable batteries. The research team has been able to prevent Li-S batteries from producing an unwanted side effect known as polysulfide dissolution that appears over time, shortening their lifespan.
