Stanford scientists identify new Li-B-S solid electrolyte materials that boost lithium-ion battery performance

Green Car Congress

The low-cost materials—made of lithium, boron and sulfur—could improve the safety and performance of electric cars, laptops and other battery-powered devices, according to the scientists. Most lithium-ion batteries today use a liquid electrolyte that can combust if the battery is punctured or short-circuited.
