| Zusammenfassung: | To provide a manufacturing method for an electrode, which can manufacture an electrode having a porous insulating layer with high uniformity without depending on a post-step such as drying or time passage even when a wet-on-wet lamination process.SOLUTION: A manufacturing method for an electrode includes: a first applying step of applying a first liquid composition including an active material and a dispersion medium on an electrode base body, thereby forming a first liquid composition layer; a second applying step of applying a second liquid composition including a polymerizable compound and a liquid on the first liquid composition layer, thereby forming a second liquid composition layer; and a polymerizing step of polymerizing the second liquid composition layer while keeping the first liquid composition layer and the second liquid composition layer, thereby forming a porous insulating layer.SELECTED DRAWING: Figure 1
【課題】ウェットオンウェット積層プロセスを用いた場合であっても、経時や乾燥時等の後工程に依存せず均一性の高い多孔質絶縁層を有する電極を製造できる電極の製造方法の提供。【解決手段】電極基体上に、活物質及び分散媒を含む第１の液体組成物を付与して第１の液体組成物層を形成する第１の付与工程と、前記第１の液体組成物層上に、重合性化合物及び液体を含む第２の液体組成物を付与して第２の液体組成物層を形成する第２の付与工程と、前記第１の液体組成物層及び前記第２の液体組成物層を維持した状態で、前記第２の液体組成物層を重合させて多孔質絶縁層を形成する重合工程と、を含む電極の製造方法。【選択図】図１ |
