Abstract

This work provides a novel strategy of optimal utilization of fluoroethylene carbonate to generate a uniform and compact solid electrolyte interface film, enhancing the cycle life of potassium ion batteries. With K foil being treated with fluoroethylene carbonate prior to use, enhanced cycling performance up to 1200 hours was achieved. Combiningin situelectrochemical impedance spectroscopy with the distribution of relaxation time analysis and XPS analysis, the solubility of KF in the electrolyte is proposed as a crucial factor to determine the quality of a solid electrolyte interface. Our work contributes to understanding the role and manipulating the usage of the fluoroethylene carbonate additive in potassium ion batteries.
