Abstract

The charge-discharge behavior of a lithium metal anode in propylene carbonate (PC) electrolyte containing added C0₂ was investigated using in situ ac impedance measurements during galvanostatic cycling. In PC electrolyte with C0₂, the anode's cycle life was twice as long and its charge transfer resistance was smaller than in the same electrolyte without C0₂. These enhancements are observed only when lithium is electrodeposited in the presence of C0₂ on nickel substrate; the enhancement does not occur when lithium is deposited without C0₂ and is cycled with C0₂. Even large amounts of H₂0 in the electrolyte during cycling do not adversely affect the cycle life enhancement by C0₂. The C0₂ enhancement seems to be due to products formed by reaction of lithium with C0₂ on the electrodeposited lithium surface.
