Scientists led by the University of Maryland in the United States have designed a new type of cathode for lithium-sulfur batteries, which they say will push the promising battery technology to higher performance levels.
Lithium-sulfur is one of many routes being pursued by scientists looking to overcome limitations to today’s lithium-ion battery technology and to develop energy storage solutions that rely on cheaper and more abundant materials. But when used as a cathode material, sulfur tends to quickly lose performance after a small number of cycles and to dissolve into sulfides in the electrolyte. The other two partners of this advanced battery project are Mercedes-Benz Research and Development North America, and Central Glass, one of the top battery electrolyte suppliers in the world. The participants will concentrate on creating a new next-generation battery development ecosystem.
