Comparative Insights and Overlooked Factors of Interphase Chemistry in Alkali Metal‐Ion Batteries

Advanced Energy Materials, EarlyView.
This review presents a comparative analysis of Li‐, Na‐, and K‐ion batteries, focusing on the critical role of electrode–electrolyte interphases. It especially highlights overlooked aspects such as SEI/CEI misconceptions, binder effects, and self‐discharge relevance, emphasizing the limitations of current understanding and offering strategies for ...

Study on the dynamic contact relationship between layers under temperature gradients in CRTSⅢ ballastless track

High-Speed Railway
In areas with large temperature differences, the uneven distribution of temperatures in the CRTS III ballastless track slab due to daytime sunlight can cause warpage deformation, leading to periodic rail irregularities that increase the wheel-rail impact

Influence of Vibration Isolator Failure on Vehicle Operation Performance and Floating Slab Track Structure Vibration Reduction Effectiveness

Shock and Vibration, 2019
At present, steel-spring floating slabs have been widely used in urban rail transit to reduce the influence of ground vibration caused by vehicle operation on the surrounding environment. As a core part of vibration reduction for floating slab track, the

Stress Analysis of Slab Track System Using Dimensional Analysis

, 2011
版式軌道是由鋼軌、扣件、混凝土版與路基組成之複雜系統，若以理想、之彈性理論進行分析將無法較精確地掌握其力學行為。而版式軌道在不考慮、以鋼筋混凝土或預力混凝土方式設計時，其型態與剛性路面之的結構型類似。因此，本研究之主要目的在以軌道力學理論為基礎，結合剛性鋪面力學分析之方式，建立新式的版式軌道力學分析方法。研究中以自由體圖之概念，將版式軌道系統分成軌道與混凝土版之模組，並分別應用軌道力學理論與剛性鋪面之版理論進行分析。本研究採用因次分析的方法，配合三維有限元素法數值運算與統計分析之方式 ...

A Quantitative Lithium Inventory Framework for Anode‐Free Lithium Metal Batteries

Advanced Energy Materials, EarlyView.
A component‐resolved lithium inventory framework quantitatively tracks Li redistribution across the cell in anode‐free NMC622||Cu pouch cells throughout cycling. Three sequential degradation stages are identified: formation‐driven cathode Li depletion, midlife inactive Li0 accumulation, and late‐stage runaway SEI thickening. The cathode, as the sole Li
