“…Various factors, such as charge‐discharge C‐rates, particle radius, electrode thickness, and the solid diffusion coefficient, significantly influence the stress levels within the particles. [ 50 ] Conditions such as high charge‐discharge C‐rates, [ 32a ] elevated voltage levels, and prolonged cycling [ 51 ] can exacerbate stress within the particles, resulting in the formation of microcracks that provide new surfaces for electrode‐electrolyte side reactions. [ 52 ] This issue is particularly significant in batteries with silicon anodes, as silicon undergoes significant volume changes during cycling.…”

Given that the non‐aqueous electrolyte in Li‐ion battery plays a specific role as an ion‐transport medium and interfacial modifier for both cathode and anode, understanding and evaluating the evolution and degradation of electrolytes throughout the life cycle is a fundamental concern within the lithium‐ion battery (LIB) community. This article provides a comprehensive overview of the electrolyte decomposition processes, mechanisms, effects of electrolyte degradation on the battery performance, characterization techniques, and modeling analysis. First, it thoroughly discusses the processes and mechanisms involved in electrolyte degradation from two primary perspectives: 1) the formation of the electrode‐electrolyte interphase and 2) the decomposition of the bulk electrolyte. Subsequently, it systematically outlines the effects of electrolyte degradation on the battery performance. The article further introduces cutting‐edge characterization and detection techniques used to assess electrolyte degradation, with a specific emphasis on quantitative methods for analyzing residual electrolytes in practical cells. Moreover, it summarizes advanced physical models of electrolyte decomposition. Finally, the paper concludes by offering insights into future trends and potential challenges in battery degradation research, it offers valuable references and guidance for further exploration of electrolyte degradation in LIBs.

“…Teichert et al [10] investigated the ageing challenges for Nirich positive electrodes, specifically focusing on the ageing mechanisms occurring in the cells, with the investigation limited to the positive electrode. Farmakis et al [11] performed interesting investigations comparing the ageing behaviour of cells with an NCA positive electrode versus pure Si or pure graphite, using standard galvanostatic cycling, and were able to conclude that a Si negative electrode was detrimental to battery lifetime. However they did not extend their investigation to include mixed materials.…”

Si-based anode materials offer significant advantages, such as high specific capacity, low voltage platform, environmental friendliness, and abundant resources, making them highly promising candidates to replace graphite anodes in the next generation of high specific energy lithium-ion batteries (LIBs). However, the commercialization of Si-based anodes for LIBs encounters significant barriers due to inherent challenges. These challenges encompass a range of issues, including poor electrical conductivity, substantial volume expansion during the lithiation−delithiation process, severe pulverization of the electrodes, pronounced thickening of the solid electrolyte interphase film, low Coulombic efficiency, and limited cycling performance. Each of these factors leads to the complexity of realizing the full potential of Si-based anodes in commercial LIBs applications. This review provides a comprehensive summary and discussion of recent research on Si-based LIB anodes, focusing on the microscopic morphology of Si and the development of Si-based composite materials. By offering a novel perspective, this review aims to provide an overview and insightful discussion of Sibased anodes. The latest research findings are presented, and innovative viewpoints and reasonable insights are addressed, shedding light on the potential solutions to overcome the limitations associated with Si-based anodes.
