Abstract
In this work,1,3-dioxolane(DOL) is originally used to pretreat the lithium metal electrode in order to passivate lithium metal and improve its interface stability.Electrochemical impedance spectra(EIS) measurements revealed that with the DOL pretreatment lithium electrode had lower and more stable interface resistance during the storage in electrolyte for a long time.And it was proved by SEM that the pretreated one has smoother morphology and less dendrite after longtime storage.Obviously,the DOL pretreatment has good passivating effects on lithium electrode.Furthermore,benefiting from the passivating effects of the stable interface film formed through DOL pretreatment,the pretreated lithium anode has higher efficiency in the repeated charge/discharge cycles.
