Among the critical needs in advanced lithium batteries, is a viable polymer electrolyte. The ideal polymer will have high ionic conductivity, chemical stability, and low cost. Proposed herein is membrane material, which meets these requirements, and has a lithium ion transfer number of one. Analogous to Nafion and comparable materials, it exhibits excellent conductivity when prepared properly, and is ideally applicable for Li polymer batteries. Phase I will be used to prepare and characterize membrane materials, and do cell-level evaluations of performance. Phase II will involve more careful material optimization and full-scale battery demonstrations. Improved Li-polymer batteries for consumer applications, electric and hybrid vehicles, and numerous military systems.
