\u200bPolymer Electrolytes for High Voltage Cathodes<\/strong>
\nGraduate Students:\u00a0ZhuoLi,\u00a0YinengZhao
\n\u200b\"\"
\nThe development of high voltage, high capacity cathodes is needed to dramatically increase the energy densities of lithium ion batteries. With these increasing cell potentials, oxidatively stable electrolytes must be employed. This is a challenge for conventional solid polymer electrolytes based on ethylene oxide functional groups, which have oxidative stability limits of about 4V. Solid polymer and gel electrolyte with high oxidative stability are being developed in our group.<\/span><\/span><\/p>\n

\u200bLi ion intercalation materials in thin film morphologies are potential protective coatings for solid-state lithium conductors. These films will protect the underlying solid from exposure to aqueous environments and inhibit potential surface reactions, while still enabling facile Li ion transport.\u00a0\u00a0\u00a0<\/span><\/p>\n

Cationic Chemical Vapor Deposition<\/span><\/strong>
Students: Dominic Giambra, Yifan Gao<\/span><\/p>\n

\u200b\"\"<\/span>Chemical vapor deposition (CVD) of polymers is an attractive process for synthesizing polymer thin films for use in optical, semiconductor, and research industries. Cationic chemical vapor deposition is a novel initiation scheme for polymer CVD developed by the Tenhaeff group that uses strong acids rather than radical species to initiate heterogeneous polymerization. The cationic process provides fast deposition rates, while eliminating thermal energy requirements.<\/span><\/p>\n

\"\"<\/span><\/p>\n

Polymer chemical vapor deposition can readily synthesize polymer thin films with\u00a0specific\u00a0optical properties. The main goal of the project is to characterize the synthesis-structure-property relationships of polymer CVD films designed for specific optical applications, and develop customized instrumentation and testing protocols to characterize the optical properties of the films under applied strain.<\/span><\/span><\/p>\n
