Dr. Adams employs his chemical engineering training towards the design, testing, and analysis of electrochemical energy storage systems. In particular, he is experienced in diagnosing lithium-ion battery failure modes induced mechanically or thermally. Additionally, Dr. Adams is well versed in electrode material synthesis and characterization, for the elucidation of structure-property relationships that correlate to lithium-ion battery performance and safety.

Dr. Adams has synthesized a variety of inorganic and carbonaceous electrodes with tunable properties, utilizing techniques such as sonochemistry, solution combustion synthesis, autogenic synthesis, and solid-state synthesis. His expertise in material characterization includes X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), thermogravimetric analysis (TGA), and others. Dr. Adams is skilled in electrochemical impedance spectroscopy (EIS), galvanostatic intermittent titration technique (GITT), and voltammetric techniques to analyze kinetic and thermodynamic properties of electrochemical systems.

Prior to joining Exponent, Dr. Adams conducted graduate research at Purdue University, where he designed electrode materials for lithium-ion batteries and next-generation potassium-ion batteries for inexpensive stationary energy storage. There he utilized differential scanning calorimetry to determine the thermal runaway mechanisms for both systems, evaluating the dependence of heat generation on cycling history and cell parameters. He also compared the influence of cycling temperature on cell aging, electrochemical kinetics, and polarization for these two systems.
