Polymer electrolytes which promote lithium ion conductivity are needed to develop advanced battery technologies for high power or high energy storage.  Polymer should be flexible with a glass transition below -70EC and an ionic conductivity greater than 10^-3S/cm.  The overall objective of this Phase I research will be to synthesize lithium ion conducting polymer electrolytes by introducing carbonate groups with one or more adjacent oxygen ions into a poly siloxane polymer matrix.  This material will achieve increased ionic conductivity and improved elastomeric properties over current state-of-the-art polymer electrolytes.  The overall goal of this Phase I program will be to synthesize carbonate-siloxane lithium ion conducting polymer electrolytes.  Upon completion of synthesis, we will perform an in-depth characterization of each polymer electrolyte.
