NICOP - Development of Hollow Nanomaterials as Highly Efficient Polysulfides Hosts for Advanced Lithium-Sulfur Batteries
Abstract
Our research encompasses the primary focus of Broad Agency Announcement, by developingadvanced functional materials for enhancing t"he properties of electrochemical power sources. Ourproposed development of a high energy density lithium-sulfur (Li-S) battery directly addresses thekey elements of this Theme.Li-S batteries show overwhelming superiorities for next-generation electrical energy storagedue to their high energy density and cost effectiveness. Enhancing the conductivity of the sulfurcathode and moderating th"e dissolution of lithium polysulfides (LiPSs) are two key factors for thesuccess of Li-S batteries. In this project, we propose to" develop polar hollow nanostructures assulfur host for Li-S batteries that overcomes both obstacles at once. Novel hollow nanostruc"tures, interms of chemical composition and shell architecture, will be designed and synthesized toeffectively restrict the dissolu"tion of LiPSs and enhance the utilization of active sulfur species forsynergistically improving the comprehensive performance of Li#NAME?"the polar shells to prevent the outward diffusion of LiPSs, which avoid the need for chemicallybonding all LiPSs on the surfaces of" polar particles.This research program will be conducted by Prof. Xiong Wen (David) Lou~s research team atNanyang Technological Un"iversity (Singapore), and involves no US collaborators. The researchresults will be presented at international/domestic conferences"" to colleagues in the field, and 2research articles will be published on top journals.
