  • IN-SITU CONTROL OF SOLID ELECTROLYTE INTERFACE FOR ENHANCED CYCLE PERFORMANCE IN LITHIUM METAL BATTERIES
    Publication number: 20220320586
    Abstract: Some aspects of the invention are related to lithium batteries, and more specifically, to in-situ control of solid electrolyte interface for enhanced cycle performance in lithium metal batteries. In some embodiments, the electrochemical cell comprises a solid electrolyte interphase (SEI) layer that is rich in inorganic materials (e.g., LiF, Li2O, Li2CO3) and has various advantageous properties (e.g., improved anode stability, etc.). Some embodiments are directed to methods of electrical energy storage and use of an electrochemical cell. In some cases, the methods comprise applying anisotropic force and/or formation voltage to a cell and forming an inorganic rich SEI layer in-situ.
