PURPOSE: A secondary battery is provided to ensure high density energy for large area and to ensure smooth electrode penetration of electrolyte due to an electrolyte flow path. CONSTITUTION: A large area stack/folding type battery comprises an electrode equipped with an electrode slurry layer(100) formed by applying electrode slurry to a current collector, and an electrode assembly(200) in which a separation film is alternated and laminated. The electrode has electrolyte flow channels(110). The electrolyte flow path is formed on the electrode slurry layer. |
