摘要:
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.

Embodiments of the invention are directed to a thin film fabricating apparatus which may be employed in mass production and may stably provide a uniform nano-order layer. An exemplary embodiment of a thin film fabricating apparatus includes: an electrode bath which contains a thin film-forming material; a plurality of needle electrodes disposed in the electrode bath; a plurality of ring electrodes disposed on the electrode bath at positions corresponding to the needle electrodes; and a substrate stand disposed opposite to the needle electrodes and the ring electrodes, where the substrate stand holds the substrate, on which a thin film is to be formed.

A coating apparatus for a traveling web comprising two coating heads and a traveling path changing roller is disclosed. A bar coater is arranged close to a pass roller. The bar coater is fixed at such a position as to contact the web when the pass roller is moved down. An extrusion coater is arranged below a backup roller in such a manner as to move up and down. If the pass roller moves up and bends up the traveling path of the web, the web separates from the bar coater. Then, if the extrusion coater moves up, the web is coated with the coating solution by the extrusion coater. If the pass roller and the extrusion coater move down, the web is coated with the coating solution by the bar coater.

Method and apparatus for curtain coating a flexible web by coating the curtain at a width wider than the width of the web. The margins of the web are preserved from being coated by conveying the web in the coating zone over a web supporting roller than does not support the web margins, and by deflecting the unsupported web margins downwardly by means of curtain interceptors that remain in contact with the web under the elastic recovery forces in the web material.
