Each year, the Institute for Materials Research Distinguished Lecture Series brings world renowned materials researchers to The Ohio State University campus to share the lastest developments in materials-allied fields and discuss their research with OSU students, faculty, and staff. IMR Distinguished Lecturers include the top scientists in their fields and this Fall we are excited to host Dr. Mark Verbrugge of General Motors Research and Development.
IMR Distinguished Lecture
“The Automotive Industry, Vehicle Electrification, and Industrial Research”
Mark W. Verbrugge, Chemical and Materials Systems Laboratory, General Motors Research and Development

1:30 PM – 2:30 PM (reception to follow)
E100 Scott Laboratory, 201 West 19th Avenue
This talk will begin with a review of automotive vehicle electrification: trends and drivers. The life of lithium-ion batteries is related to the mechanical expansion and contraction of the active materials along with solvent decomposition at the active material surfaces—lithium-ion batteries would not work if a protective shell did not cover the electroactive core of the positive and negative electrode materials. Exposure of the active core leads to cell degradation. These observations hold for current and next-generation lithium-ion batteries. Under what conditions are the protective (outer shell) materials compromised? In addition to reviewing literature that is relevant to answering this question, the speaker intends to overview research results to render a qualitative response to this question and identify open questions that limit the quantitative application of modeling results to these systems. Last, we will close with a brief perspective on “what is useful industrial research?”
