Session: PMSE/POLY Poster Session:

Polymers have potential to create safe and effective electrolytes for lithium ion batteries. However, most state-of-the-art polymer electrolytes suffer from low room temperature conductivity and have transference numbers less than 0.5. These problems stem from the lithium ion mobility being coupled to the segmental motion of the polymer matrix. A possible solution is single ion conducting polymers, in which the anions are covalently bound to the polymer backbone. Herein we present novel single ion conducting polymers that have anions precisely spaced along a polyethylene backbone. This allows for crystallization driven self-assembly creating anionic channels. We show that these self-assembled structures form robust films capable of ion conduction that is decoupled from the crystalline polymer matrix.
