Synthesis of Lithium Thin Film by Electrodeposition from Ionic Liquid

Abstract:

Synthesis of metallic lithium thin film was investigated from two ionic liquid of [EMIM]Tf2N and PP13Tf2N with LiTFSI as a lithium source. Cyclic voltammograms on Au electrode showed the possibility of the electrodeposition of metallic lithium, the reduction current in [EMIM]Tf2N was higher than the value in PP13Tf2N. The metallic lithium thin film could be synthesized on the Au electrode by the potentiostatic condition, which was confirmed by various analytical techniques including x-ray diffraction and scanning electron microscopy with energy dispersive spectroscopy. The lithium surface electrodeposited was uniformly without dendrite, any impurity was not detected except trace oxygen contaminated during handling for analyses.
