Higher Capacity Lithium-Ion Battery
A novel lithium-ion battery design that includes tin, sulfur, and a polymer outperforms today's commercial units in terms of charge-storage capacity, according to chemists in Italy who designed the device (Angew. Chem. Int. Ed., DOI: 10.1002/anie.200907324). For years, researchers have known that lithium-sulfur-based batteries are capable of packing more power per size and weight than commercial batteries made with lithium/transition-metal oxide cathodes and carbon-based anodes. Yet progress in developing suitably safe, stable, and long-lasting versions . . .
