Problems solved by technology

[0011] However, in the method of using the conventional droplet ejection device, there is a problem that if the droplets of different types of compositions are applied close to each other, wetting will occur at the boundary thereof, causing the pattern to be damaged. destroyed, so that the desired pattern cannot be formed

Embodiment Construction

[0047] The present invention will be described in detail below with reference to the accompanying drawings.

[0048]

[0049] In the method for forming a functional film of the present invention, two or more functional materials are ejected onto the substrate by a droplet ejection device, thereby forming a functional film composed of two or more functional materials. The forming method is characterized in that according to a pre-designed coating pattern, the functional material with the relatively smallest coating area among the two or more functional materials is first coated on the substrate, and then the functional material with a relatively large coating area is coated. permanent material, thereby forming a functional film with a predetermined pattern.

[0050] Here, the term "pattern" refers to the design of which regions on the substrate to attach two or more functional materials having different functions. Patterns are designed semi-empirically to obtain functional f...

Abstract

A method is provided for forming a functional film having at least first and second functional materials arranged in accordance with a prescribed coating pattern on a substrate. The method includes discharging the first functional material having a smaller coating surface area than the second functional material according to the prescribed coating pattern onto the substrate using a droplet discharge apparatus, and discharging the second functional material according to the prescribed coating pattern onto the substrate using the droplet discharge apparatus after the first functional material is discharged onto the substrate.

Description

technical field [0001] The present invention relates to a method for forming a functional film that uses a droplet discharge device to separately discharge two or more functional materials onto a substrate to form a functional film having a predetermined pattern, a method for manufacturing an electrode using the method, and a method for using the same. The manufacturing method of the secondary battery of the manufacturing method of an electrode. Background technique [0002] In recent years, with the introduction of electric vehicles (EV), hybrid electric vehicles (HEV), and fuel cell vehicles (FCV), the development of batteries that serve as power sources for these vehicles has also been rapidly developed. These batteries have very strict conditions such as being able to be repeatedly charged and discharged, and being able to achieve high output and high energy density. In order to meet the above requirements, Patent Document 1 proposes to manufacture a thin laminated batt...
