CPOS Seminar: "Convergent high conductivity of small-ligand-containing solid-state polymer electrolytes"
Speaker: LUANA LLANES, Graduate Student Researcher, Chemistry and Biochemistry Department, UCSB
Abstract: Lithium ion batteries are essential to modern society and the subject of continued research efforts towards improving their safety and energy density. Presently, the vast majority of modern LIBs employ liquid electrolytes despite their inherent safety concerns including leakage and flammability. Solid state electrolytes offer a safer alternative, however these systems need to be further studied to improve the conductivity and selective conduction of Li+. In this study, polymethylsiloxane, a low glass transition temperature polymer, which affords fast segmental dynamics has been functionalized with small, polar, non-hindered ligands to facilitate ion solvation and transport. These systems offer improved performance over several existing solid electrolytes while allowing us to further understand the structure-properties relationship governing ion mobility.
