摘要：

Electrodeposited lithium produced with and without CO2 in LiClO4/propylene carbonate electrolytes was investigated for charge-discharge cycleability, surface morphology, and composition of he surface layer. The addition of CO2 in the electrolyte enhances the cycleability, produces smoother surface morphology, and forms Li2CO3 in the inner region of the surface film. This paper describes experimental results showing those three different effects of CO2 addition, and discusses the interrelation among them.
