Mechanical Engineering MS Thesis Defense by Mr. Roger H. Tessier, Jr.

Friday, December 05, 2025 at 2:00pm to 4:00pm

The pursuit of structural supercapacitors lies at the forefront of next-generation energy storage, demanding electrolytes that combine high ionic conductivity with mechanical stiffness.  Reconciling these properties has remained a formidable challenge.  This thesis advances the field by developing a single-phase PET/LiTFSI solid polymer electrolyte, fabricated through humidity-controlled injection molding and melt casting, and subsequently tuned through controlled uptake of water and organic solvents using a custom-designed vapor-enclosure system not reported elsewhere in the literature.
