Dr. Joseph Hadden's expertise is in the electrochemistry of materials and lithium-ion batteries. During his time at Exponent, his work has focused on electronic devices with an emphasis on lithium-ion battery failure analysis, as well as corrosion and materials analysis for a variety of applications such as consumer electronics and the transportation industry. Dr. Hadden has an extensive background in materials characterization using a wide range of analytical techniques including X-ray computed tomography (CT), electron microscopy, X-ray diffraction (XRD), time of flight secondary ion mass spectrometry (ToF-SIMS), infra-red (IR) spectroscopy, and scanning ion-conductance microscopy (SICM). As well as electrochemical techniques such as electrochemical impedance spectroscopy (EIS) and various battery characterization tests.

Prior to joining Exponent, Dr. Hadden was a postgraduate Research Associate at Imperial College London. His research areas included, photoelectrochemical actuation, electrocatalysis for water splitting, and electrode materials for Li-ion batteries. His most recent work focused on studying the degradation of Li-ion battery electrodes using scanning ion-conductance microscopy.

Dr. Hadden retains these links to academia through a visiting researcher position at Imperial College London. Dr. Hadden's PhD was in the field of electrochemical capacitors, with a focus on the synthesis and characterization of mixed metal oxide nanomaterials. His work studied the structure/function relationship of these materials to elucidate their underlying charging mechanisms.
