Impacts of Lithium Salt on Interfacial Reactions between SiO and Ethlyene Carbonate-Based Solutions in Lithium Secondary Batteries

Abstract:

This study investigates the influence of lithium salt on the interfacial reactions that occur between SiO and ethylene carbonate-based solutions in lithium secondary batteries. Electrochemical reactions occurring at a SiO electrode were examined to gain insights into the effects of lithium salts, such as LiPF₆, LiBF₄, LiClO₄, and LiCF₃SO₃, on the interfacial resistance. The SiO electrode exhibited a relatively high reversible capacity and Coulomb efficiency in an electrolyte solution containing LiCF₃SO₃. The interfacial resistance was the highest in the solution containing LiPF₆ and the lowest in the solution containing LiBF₄. The findings from this investigation are expected to offer valuable insights for optimizing the design and performance of lithium secondary batteries by manipulating interfacial reactions.
