Dr. Cohn specializes in failure analysis, material characterization, material synthesis, and electrochemical testing. His expertise includes battery design and testing, with experience working on a range of current and emerging battery chemistries.
Dr. Cohn has experience characterizing materials using Raman spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and UV-visible spectroscopy (UV-Vis). He also has experience with a range of synthesis and deposition techniques, including sol-gel synthesis, wet-chemical synthesis, hydrothermal synthesis, solid-state synthesis, aluminum anodization, chemical vapor deposition (CVD), and atomic layer deposition (ALD).
As a National Science Foundation Graduate Research Fellow at Vanderbilt University, Dr. Cohn’s research was focused on the design, development and characterization of new battery chemistries, including sodium-ion and sodium metal systems for low-cost stationary energy storage. In addition, Dr. Cohn worked on the development of low-power color display technology utilizing electrochemical actuation, as well as the development of a solar-powered supercapacitor for mitigating the problem of renewable power intermittency.
