Lithium-ion battery innovation takes a leap forward with the Journal of The Electrochemical Society (JES)’s illuminating new article, “Main Ageing Mechanism of SiOx-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…)
