Research Abstract

The electrolytic conductivity and charge-discharge characteristics of the lithium electrode were examined in the ternary solvent systems made up of ethylene carbonate (EC)-dimethylcarbonate (DMC) equimolar binary mixture with 3-mehylsydnone (3-MSD) and 3-ethylsydnone (3-ESD). The electrolytes used are LiClO_4, LiPF_6, LiBF_4, LiCF_3SO_3, LiN(CF_3SO_2)_2, and LiN(C_2F_5SO_2)_2. The order of the decrease in conductivities of ternary solvent electrolytes at mol ratio 0.5 of 3-MSD and 3-ESD is LiPF_6>LiClO_4>LiN(CF_3SO_2)_2 and LiN(C_2F_5SO_2)_2>LiBF_4>LiCF_3SO_3. The 1 mol dm^<-3> LiN(CF_3SO_2)_2 and LiN(C_2F_5SO_2)_2 electrolytes with large anions show the moderate conductivities of more than 6-7 mS cm^<-1> at mol ratio 0.5 of 3-MSD and 3-ESD.An addition of 3-MSD and 3-ESD to the EC-DMC equimolar binary mixture containing LiClO_4, LiBF_4, LiCF_3SO_3, and LiN(CF_3SO_2) is effective for the rise in lithium electrode cycling efficiency. It is found by using scanning electron microscope (SEM) that the cycling efficiency is dependent on the morphology and thickness of the film formed on the Ni (working) electrode. In addition, the film was found to be containing a certain nitrogen compound by using X-ray photoelectron spectroscope (XPS).
