Effects of Lithium Salt on Interfacial Reactions between SiC and EC-Based Solutions in Lithium Secondary Batteries

Abstract:

Electrochemical reactions occurring at a SiC electrode were investigated to gain insight into the effects of lithium salts, such as LiPF₆, LiClO₄, LiCF₃SO₃, and LiBF₄, on the interfacial resistance. Lithium salts were found to exert little effect on the magnitude of the resistance of the solid-electrolyte interphase (SEI). In contrast, the charge-transfer reactions observed in the LiCF₃SO₃-containing solution exhibited the smallest resistance. Charge-discharge analysis revealed that the nature of the SEI was significantly different from that formed in ethylene carbonate-based solutions containing different lithium salts. The SiC electrode exhibited large discharge capacity and low coulombic efficiency in the LiCF₃SO₃-containing solution. This might be closely related to the smallest charge-transfer resistance.
