Fraunhofer researchers report significant extension to Li-S cycle life with silicon anodes and CNT-sulfur composite cathodes

Green Car Congress

According to Dr. Holger Althues, head of the Chemical Surface Technology group at IWS, by using the combination of silicon anode and composite carbon nanotube/sulfur cathode materials, the team has extended the cycle life of lithium-sulfur button cells from 200 cycles to 1,400 cycles.
