Publication number: 20240113388Abstract: Lithium-sulfur (Li—S) batteries using unconventional-phase transition metal dichalcogenides (TMDs), such as 1T?-WS2, as the functional layer on the separator. The unique atomic structure of 1T?-WS2 facilitates the strong immobilization and excellent catalytic ability in the conversion of polysulfide intermediates during cycling. Furthermore, the self-assembling of 1T?-WS2 greatly decreases the internal porosity, minimizing the uptake of electrolyte, which can further guarantee the performance of the battery under lean electrolyte conditions. As a result, a cell based on the 1T?-WS2 shows improved performances under high sulfur loading and lean electrolyte conditions. A cell with 12 mg cm?2 mass loading of S with only 25% oversized Li metal anode can deliver specific energy of at least 400 Wh kg?1 and 820 Wh L?1, which is among the best of reported Li—S batteries.Type: ApplicationFiled: September 27, 2023Publication date: April 4, 2024Inventors: Hua ZHANG, Zijian ZHENG, Zhuangchai LAI, Lei WANG
