Abstract: Disclosed are an electrode material for a secondary battery and a method of manufacturing the electrode material, capable of reducing lithium side reactions, simplifying processes, and reducing cracks caused by external impact. The electrode material for a secondary battery includes a bonding sheet, an active material layer, and a current collector. The bonding sheet includes a plurality of through-holes penetrating first and second surfaces opposite to each other. The active material layer includes a first layer covering the first surface, a second layer covering the second surface, and a connecting layer formed inside the through-holes to connect the first layer and the second layer. The current collector is attached to the second layer.

Abstract: An electrode for a secondary battery and a method for manufacturing the same are disclosed, which reduces lithium side reactions, has a simple process, and can reduce cracks caused by external impact. The electrode material for a secondary battery according to an exemplary embodiment of the present invention comprises a base film with a plurality of through holes, a binder and a current collector. The binder includes active material particles dispersed therein and is fixed to the through holes. The current collector is attached to the base film.

Abstract: Provided are a polyimide film capable of reducing a dielectric constant of a substrate and reducing a thickness and forming a stable via with a low possibility of disconnection, a method for manufacturing the same, and an FPCB including the same. A polyimide film according to an exemplary embodiment of the present invention includes a polyimide layer and a plurality of fluororesin particles dispersed in the polyimide layer. The fluororesin particles have a spherical or flat shape.
