Kusoglu Lab Research

Our research theme is the structure-property characterization and modeling of ionomers and solid-polymer electrolytes to understand and improve their stability & functionality in electrochemical technologies - from the polymer-electrolyte and alkaline fuel cells to electrolyzers and flow batteries.

Our research approach involves data-driven design and understanding of ion-containing polymers (ionomers) and thin films at electrode interfaces, including interrogation of their transport functionality and mechanical stability as well as morphological characterization through state-of-the-art synchrotron X-ray techniques at the Advanced Light Source (ALS).

  • Structure-Function relationships of ionic polymers for energy conversion devices

    • Understanding transport-stability correlations in anion- and cation-exchange membranes
    • Development of characterization techniques for morphology, transport function and mechanical deformation of functional polymers (with the ALS)
