Silica-based cathode enables long-life Li-S batteries

Green Car Congress

Scientists from the Daegu Gyeongbuk Institute of Science and Technology, Korea, have developed a novel silica-based cathode for lithiumsulfur batteries, thereby enabling the realization of batteries that can last for more than 2,000 charge/discharge cycles. However, carbon-based hosts cannot trap LiPS. —Prof Yu.
