Understanding fluorine-free electrolytes via small-angle X-ray scattering
文献摘要：
Fluorine-free electrolytes have attracted great attention because of its low-cost and environmental friendliness.However,so far,little is known about the solution structures of these electrolytes.Here,we compare the solvation phenomenon of sodium tetraphenylborate(NaBPh4)salt dissolved in organic solvents of propylene carbonate(PC),1,2-dimethoxyethane(DME),acetonitrile(ACN)and tetrahydrofu-ran(THF).Small-angle X-ray scattering(SAXS)reveals a unique two-peak structural feature in this salt-concentrated PC electrolyte,while solutions using other solvents only have one scattering peak.Molecular dynamics(MD)simulations further reveal that there are anion-based clusters in addition to the short-range charge ordering in the concentrated NaBPh4/PC electrolyte.Raman spectroscopy con-firms the existence of considerable contact ion pairs(CIPs).This work emphasizes the importance of glo-bal and local structural analysis,which will provide valuable clues for understanding the structure-performance relationship of electrolytes.
