Abstract
Methods, systems, and compositions for the solution-phase deposition of thin films that form artificial SEIs on conversion anodes in lithium-ion batteries. In certain aspects, the solution-phase deposition methods comprise sequentially processing a lithium-ion conversion anode with multiple liquid reagents to form a monolayer or stacks of monolayers forming the thin film coating. The conversion anodes produced by the methods and systems described herein have a surface coating that is electrically insulating, consumes little to no lithium, is permeable to lithium transport, is impermeable to electrolyte and is mechanically robust against volumetric expansion.
