Graphene sponge helps lithium sulphur batteries reach new potential

(Chalmers University of Technology) To meet the demands of an electric future, new battery technologies will be essential. One option is lithium sulfur batteries, which offer a theoretical energy density more than five times that of lithium ion batteries. Researchers at Chalmers University of Technology, Sweden, recently unveiled a promising breakthrough for this type of battery, using a catholyte with the help of a graphene sponge.
