Solution-phase electrodeposition of artificial solid electrolyte interphase (sei) layers on battery electrodes

Abstract

Methods, systems, and related aspects for solution -phase electrodeposition of artificial solid- electrolyte interphase (SEI) layers coated onto battery electrodes. In certain aspects, such a method comprises: (a) providing the battery electrode onto a conveyance apparatus; (b) transferring, by the conveyance apparatus, the battery electrode to an electrodeposition chamber containing a liquid solution comprising a first reagent and an electrolyte; exposing the battery electrode to the liquid solution; and applying a voltage or current to the battery electrode relative to a counter electrode exposed to the liquid solution for a predetermined amount of time, thereby yielding a coated battery electrode comprising the artificial SEI.
