ASM West Michigan (Grand Rapids) Chapter Community

FEATURE PRESENTATION: Increased demand for portable consumer electronics has fueled the need for inexpensive, high energy-dense rechargeable batteries primarily containing lithium-ion technology. Over the past several years there have been many high profile examples in the news of what can go wrong when these batteries fail, causing property damage, health hazards, and product recalls. This presentation is focused at discussing failure modes and common causes within the lithium-ion battery industry and how failure analysis can assist in diagnosing problems either before or after a failure has occurred.

SPEAKER BIO: Jesse Ondersma, PhD, is department manager at Intertek, a global industry leader in third party testing and consulting.  Jesse is the technical lead for advanced battery failure analysis (FA) and air quality analytical chemistry testing. At Intertek he developed their procedure for inert disassembly and inspection of lithium ion batteries within their failure analysis service. This FA service can include inspection by optical microscopy, scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDS), gas chromatography / mass-spectrometry (GC/MS), and electrochemical impedance spectroscopy (EIS) among other techniques. Jesse holds a B.S. in Chemistry from Grand Valley State University and a Ph.D. in Chemistry from Michigan State University where his research involved quantifying and controlling electrochemical reactions and electron transfer at semiconductor/electrolyte interfaces.
