Electrochemical behaviors of li electrode in organic electrolytes

Abstract

Characterizations of the morphology of lithium deposited in organic electrolytes were carried out using Ni substrates pretreated with H: and CO2 gases prior to electrodeposition. The electrolytes used were 1 M LiC1OdEC-2MeTHF and 1 M LiPFJEC-2MeTHF. Based on electrochemical measurements, XPS and SEM analyses, it seems that the morphology of lithium during electrodeposition is related to the physical propenies of the electrolyte itself rather than the chemical composition of a passive layer formed on the lithium surface.

“…Poly(ethylene oxide) (PEO) polymer electrolytes have weaknesses such as poor mechanical properties at higher temperature and poor ionic conductivity at low ambient temperature for lithium polymer batteries [1]. Several well known methods have been utilized to resolve these problems.…”
