We’re thrilled to recognize one of the top-read articles in the Journal of The Electrochemical Society (JES): “Changes in Structure and Ionic Resistance of Lithium-Ion Battery Graphite Electrodes – Part I: Impact of Formation and SEI” by Jonas L. S. Dickmanns, Lennart Reuter, Robert Morasch, Filippo Maglia, Roland Jung, and Hubert A. Gasteiger.
This study dives into the structural evolution of graphite electrodes during the formation process of lithium-ion batteries—particularly the development of the solid electrolyte interphase (SEI). The authors provide a detailed, quantitative understanding of how this formation process impacts porosity, tortuosity, and thickness, ultimately increasing ionic resistance by up to 25 percent. These findings are essential for researchers and engineers seeking to design batteries that are not only more energy-dense, but also more efficient and durable. (more…)
