Graphical Abstract

Li-Ion Batteries

In article number 2500131, Asif Latief Bhat and Yu-Sheng Su illustrate the sponge-like structural evolution of silicon anode particles during cycling, which coincides with the onset of Coulombic efficiency troughs. The study identifies key factors such as electrode thickness, voltage window, and electrolyte composition that govern this phenomenon, providing new insights to guide the design of stable and high-performance silicon-based lithium-ion batteries.
