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.
