Secondary battery electrode, and method for producing same
摘要
說明書
When one or more electrodes selected from a positive electrode and a negative electrode are a negative electrode, in the negative electrode, the active material film containing the negative electrode active material is adhered to at least one surface of the current collector by an adhesive. That is, the lithium secondary battery according to an exemplary embodiment of the present invention may include a positive electrode; a negative electrode in which the active material film containing a negative electrode active material is adhered to at least one surface of the current collector by an adhesive; a separator interposed between the positive electrode and the negative electrode; and an electrolyte solution. Here, the positive electrode may include a positive electrode active material disposed on the current collector, the positive electrode active material in the positive electrode active material layer may be any material capable of reversible desorption/intercalation of lithium ions, and may be any electrode material used in the positive electrode of the common lithium secondary battery. As an example, the positive electrode active material may be an oxide having a layered structure represented by LiCoC2, an oxide having a spinel structure represented by LiMn2O4, or a phosphate-based material having an olivine structure represented by LiFePO4.
