Interphasial chemistry
WebNov 20, 2015 · Summarizing all the spectra information, an overall picture of the Li + solvation sheath and its role in interphasial chemistry emerges. In dilute solutions (< 5 m) ( 34 , 35 ), the abundance of water can afford a conventional solvation sheath structure (i.e., four water molecules per Li + in the primary and more in the loosely bound secondary … WebSilicon (Si) has gained huge attention as an anode material for next-generation high-capacity lithium-ion batteries (LIBs). However, despite its overwhelming beneficial features, its large-scale commercialization is hampered due to unavoidable challenges such as colossal volume change during (de)alloying, inherent low electronic and ionic …
