摘要： Articles and methods involving electrochemical cells and/or electrochemical cell preproducts comprising passivating agents are generally provided. In certain embodiments, an electrochemical cell includes first and second passivating agents. In some embodiments, an electrochemical cell may include a first electrode comprising a first surface, a second electrode (e.g., a counter electrode with respect to the first electrode) comprising a second surface, a first passivating agent configured and arranged to passivate the first surface, and a second passivating agent configured and arranged to passivate the second surface.

摘要： 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.
