Abstract

The reactivity of poly(vinylidene-co-hexafluoropropylene) (PVdF/HFP)-based gel polymer electrolytes towards a lithium electrode was studied by AC impedance spectroscopy technique. PVdF/HFP-based gel polymer electrolyte (GPE) was formed by immobilizing the lithium hexafluorophospate (LiPF6) in a mixture of ethylene carbonate-dimethyl carbonate (EC-DMC) liquid electrolyte in the copolymer matrix. The impedance measurement was run during 10 days storage of a cell of Li/gel polymer electrolyte/Li. Results obtained were used to identify charge-transfer resistance, double layer capacitance and properties of passivation films. Ceramic filler of SnO2 was introduced in the system in attention to improve the transport properties as well as to reduce the reactivity towards lithium electrode.
