Jenny T. Beach, Ph.D.
Senior Associate
Materials & Corrosion Engineering
Menlo Park

Dr. Beach is formally trained as a materials scientist with a focus on surface chemical and structural evolution of commercial electrode materials in rechargeable Li-ion batteries. She specializes in determining the fundamental mechanisms governing the poor cycle life and failure of Li-ion batteries through in situ methods. Dr. Beach is knowledgeable in electrochemistry, battery failure analysis, material characterization, and intrinsic material properties. Her experiences include using scanning electron microscopy (SEM) and transmission electron microscopy (TEM) for microstructure determination, and using X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES) for surface chemistry evaluation. Additionally, she has familiarity with electrochemical characterization techniques for Li-ion battery testing, as well as composite electrode preparation and coin cell fabrication.

Prior to joining Exponent, Dr. Beach completed her Ph.D. at the department of Materials Science and Engineering at the University of Illinois at Urbana-Champaign under the supervision of Professor Shen Dillon. She developed a novel cross-platform in situ open cell approach to carry out a study of commercially relevant anodes and cathodes using SEM, XPS and AES. She utilized this open cell design to study the mechanism of lithium dendrite growth during deposition on carbon anodes, a condition that can lead to thermal runaway and is one of the safety concerns for current Li-ion batteries. She also utilized the in situ cell to characterize the nature of surface reactions occurring on a series of cathode materials as a function of potential and cycle number, which resulted in new paradigms for understanding surface reactions driving cathode degradation. Additionally, Dr. Beach worked closely with the scientists at the Materials Research Laboratory in Urbana to develop custom cell format and an experimental methodology to study the surface evolution of electrode materials with powerful surface sensitive spectroscopies.
