The present disclosure relates to a method of forming a composite article. The method includes: providing a structural component with a surface, wherein the surface includes a silicone elastomer, a fluoropolymer, or a copolymer or a block copolymer; optionally pre-treating the surface with a plasma treatment; coating the surface of the structural component with a precursor coating component, wherein the precursor coating component including a polyvinyl alcohol based component, and treating the precursor coating component to form a crosslinked coating layer overlying the surface of the structural component.

An active material coating method includes: forming first and second coating lines on a first surface of a base material; forming a first active material coating layer between the first and second coating lines on the first surface of the base material; forming third and fourth coating lines on a second surface of the base material; forming second active material coating layer between the third and fourth coating lines on the second surface of the base material; forming a first etched active material coating layer by etching a part of the first active material coating layer; determining a positional relationship between the first etched active material coating layer on the first surface and the second active material coating layer on the second surface; and forming a second etched active material coating layer by etching a part of the second active material coating layer based on the positional relationship.

Provided is an aqueous coating composition that can exhibit high coating film performance even when cured at a relatively low temperature. The present invention pertains to an aqueous coating composition comprising (A) a hydroxyl group-containing resin and (B) a blocked polyisocyanate compound. The weight average molecular weight of the blocked polyisocyanate compound (B) is in a range of 20,000-200,000.

The present technology relates to an electrode manufacturing system, and an electrode manufacturing method using the same. According to the present technology, it is possible to uniformly second-coating an electrode slurry as an electrode current collector, which has gone through electrode slurry first coating and drying processes, passes through a heat pipe guide roller.
