Patent ID: 11196038

Abstract:
Provided is a method for manufacturing a flexible electrode, including the steps of: (i) coating a porous current collector having a plurality of pores with an active material slurry having a solid content of 30-50% and drying the active material slurry to form an active material coating layer; (ii) coating an active material slurry having a solid content of 30-50% on the active material coating layer formed from the preceding step and drying the active material slurry to form an additional active material coating layer; and (iii) repeating step (ii) n times (1≤n≤5) to form multiple active material coating layers, thereby forming an electrode active material layer in the pores and on the surface of the porous current collector in a non-press mode. A flexible electrode obtained from the method and a lithium secondary battery including the flexible electrode are also provided.
