This three-year National Science Foundation project grant of $517,023 will fund research at Tufts University into lithium ion transport in self-assembled zwitterionic nanochannels containing ionic liquids for next-generation energy storage applications. The research aims to study lithium ion movement within zwitterionic conducting nanochannels formed by self-assembly of amphiphilic comb copolymers. These nanostructured electrolytes will be swollen with controlled amounts of a nonvolatile ionic liquid containing dissolved lithium salt. Characterization techniques like AC impedance spectroscopy, DC polarization measurements, pulsed field gradient NMR spectroscopy, and electrophoretic NMR spectroscopy will examine the effect of zwitterionic side groups on lithium ion transport as nanochannel size is modulated. The project falls under the National Science Foundation's Engineering Directorate and its CFDA program titled Engineering, which seeks to foster innovation and excellence in engineering research.
