Abstract:
Methods, systems, and compositions for the liquid-phase deposition (LPD) of thin films. The thin films can be coated onto the surface of porous components of electrochemical devices, such as battery electrodes. Embodiments of the present disclosure achieve a faster, safer, and more cost-effective means for forming uniform, conformal layers on non-planar microstructures than known methods. In one aspect, the methods and systems involve exposing the component to be coated to different liquid reagents in sequential processing steps, with optional intervening rinsing and drying steps. Processing may occur in a single reaction chamber or multiple reaction chambers.

Claim (Index 1):
A liquid phase deposition method for generating an artificial solid-electrolyte interphase (SEI) on a surface of an active material of a lithium-ion battery electrode, comprising:\n (a) providing the lithium-ion battery electrode comprising the active material onto a roll-to-roll conveyance apparatus; (b) transferring, by the conveyance apparatus, the lithium-ion battery electrode to a first reaction chamber containing a first liquid solution comprising at least a first reagent; (c) exposing, by the conveyance apparatus, the lithium-ion battery electrode to the first liquid solution in the first reaction chamber to yield a partially coated layer of the artificial SEI with the at least first reagent chemically bonded onto the surface of the active material and an unreacted first reagent; (d) rinsing, in the first reaction chamber, the layer with a first rinsing solution comprising a first solvent to remove the unreacted first reagent; (e) transferring, by the conveyance apparatus, the lithium-ion battery electrode from (d) to a second reaction chamber containing a second liquid solution comprising at least a second reagent, (f) exposing, by the conveyance apparatus, the lithium-ion battery electrode to the second liquid solution in the second reaction chamber, wherein the at least second reagent reacts with the at least first reagent chemically bonded onto the surface of the active material to produce the artificial SEI comprising a monolayer on the surface of the active material, the monolayer comprising a compound generated from the reaction of the at least second reagent and the first reagent, and an unreacted second reagent; and (g) rinsing, in the second reaction chamber, the coating with a second rinsing solution comprising a second solvent to remove the unreacted second reagent.
