Fang, Chen published the artcileGradient polarity solvent wash for separation and analysis of electrolyte decomposition products on electrode surfaces, Application In Synthesis of 142-90-5, the main research area is LIB electrode SEI analysis gradient polarity solvent wash.
The solid electrolyte interphase (SEI) formed during the cycling of lithium-ion batteries (LIBs) by decomposition of electrolyte mols. has key impact on device performance. However, the detailed decomposition process and distribution of products remain a mystery due to the wide variety of electrochem. pathways and the lack of facile anal. methods for chem. characterization of SEIs. In this report, a gradient polarity solvent wash technique involving the use of solvents with gradually increased polarities is employed to sequentially remove different SEI components from electrode surfaces. Fourier transform IR (FTIR) spectroscopy is utilized to characterize the SEI composition The impacts of electrolyte additives and discharge rates over SEI formation are illustrated. This study presents a new concept of rationally controlled solvent wash technique for electrode surface anal. that can selectively remove targeted components. The findings in this study provide exptl. support for the slow charge formation processes commonly employed for LIBs in industry.
