Over the past two decades, solid–electrolyte interphase (SEI) layer that forms on an electrode's surface has been believed to be pivotal for stabilizing performance in lithium-ion batteries (LIBs). However, more and researchers currently are realizing metal-ion solvation structure (e.g., Li+) electrolytes derived interfacial model (i.e., desolvation process) can affect significantly. Thus, herein we summarize recent research focused how discover importance of electrolyte's structure, develop...

Via different annealing process, these precursors can be converted into MoO2 /C Mo2 C/C composites without any distortion shape. Owing to well-organized nanosize particle embedding, as-prepared exhibit appealing...
