Abstract

Sydnone is known as a typical mesoionic compound, which can be represented by the resonance hybrid of different polarized ionic structures. We have newly synthesized 3-methyl-4-acetylsydnone (3-MASD) and describe the thermal characteristics. We have also investigated the physicochemical properties of 3-MASD – based binary solutions and the addition effect of the 3-MASD on cycling efficiency of a lithium anode in ethylene carbonate (EC) – chain ester (mole ratio 1 : 1) systems. The addition of the 3-MASD in a mole ratio of 0.05 is found to be the most effective for an increase of the cycling efficiency.
