Automated, High Throughput Screening of Increased Ionic Conductivity Polymer Electrolytes

Webinar Details:

Advancement of increased ionic conductivity polymer electrolyte materials for Li-ion battery applications has traditionally required formulations to be hand-mixed by researchers, limiting progress and adding potential batch-to-batch variability. Through our Studying-Polymers-On a-Chip (SPOC) platform, we seek to solve the challenge of developing safe, stable, and cost effective batteries. We do so by accelerating screening of polymer electrolyte materials through integration of additive manufacturing, impedance characterization, and machine learning experimental planning systems. Various monomers, salts, and nanoparticle fillers were screened to modify the amorphous character in semicrystalline polyethylene glycol-based polymer electrolytes. Ultimately, long-term cycling, aging, and stability measurements need to be made for identified polymer electrolytes to be useful for battery applications. The end of the talk will discuss some of our ongoing SPOC platform developments to create and couple high-throughput aging and degradation assessments into our screening platform.
