The Journal of The Electrochemical Society (JES) proudly celebrates the rapid success of the open access article “Understanding Lithium Deposition in Lithium-Ion Batteries: The Link between Impedance Results and Electrochemical Behavior.” In just a few short weeks since publication, this paper has risen to the top of JES’s Most Read Articles of 2025, capturing global attention for its clarity, rigor, and real-world relevance.

Illuminating Lithium Deposition

Lithium deposition, or plating, remains a major challenge in advancing lithium-ion batteries. When metallic lithium forms during fast charging or under non-ideal conditions, it can cause dendrites, capacity loss, and safety risks. This groundbreaking study offers fresh insight by directly linking impedance spectroscopy results to electrochemical deposition behavior, providing researchers with a predictive framework to better understand and control plating phenomena.

By connecting impedance signals with changes in morphology and capacity, the authors reveal when and how lithium deposition occurs. Their work identifies spectral features associated with plating onset, evolving interfacial kinetics, and irreversible capacity fade—insights that will guide the design of safer and more durable energy storage systems.

Lithium-ion battery innovation takes a leap forward with the Journal of The Electrochemical Society (JES)’s illuminating new article, “Main Ageing Mechanism of SiO_x-Graphite Anodes during Fast Charging in the Absence of Lithium Deposition,” by  Hao-Chen Hsiao, Alexander Adam, Daniel Goldbach, Yichen Dai, Jiahao Li, Thomas Waldmann, and Markus Hölzle.

This study rigorously uncovers the primary aging culprit—the irreversible loss of over 20 percent of cyclable lithium after just 400 equivalent full cycles—even when lithium plating is absent. (more…)

The Electrochemical Society (ECS) proudly celebrates the continued success of “Origin and Innovations of CMP Slurry” by Dr. Hitoshi Morinaga, published in the ECS Journal of Solid State Science and Technology (JSS) as part of the Focus Collection, “Chemical Mechanical Planarization (CMP): Past, Present, and Future in Honor of S. V. Babu” (DOI: 10.1149/2162-8777/ad5fb6).

Since its publication just over a year ago, Dr. Morinaga’s article has remained on JSS’s most-read list, earning over 6,000 downloads and seven Web of Science citations. A dedicated ECS member since 1999, and an active contributor to the ECS Electronics and Photonics Division and ECS Japan Section, Dr. Morinaga’s work reflects both technical excellence and deep engagement with our community.

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…)
