In the present invention, an improved electrode so that lithium ions move smoothly to an active material, a lithium secondary battery including the same, and a method for rapidly manufacturing such an electrode are provided. The electrode according to the present invention includes a current collector; Including a porous polymer structure formed on the current collector, the porous polymer structure, a porous PVDF-HFP (Poly (vinylidene fluoride-co-hexafluoropropylene) film; And an active material and a conductive material included in the porous PVDF-HFP film According to the present invention, by minimizing physical adhesion between the active material and the binder, the area in which lithium ions can react with the active material is maximized. Accordingly, a lithium secondary battery including such an electrode can be quickly charged/discharged. It is possible to increase the performance such as capacity conservation. |
