Abstract
An electrode for a lithium secondary battery includes a current collector, primer layer formed on a side of the current collector and includes a first conductive agent, a first binder and a first dispersant. Further, an active material layer is formed on a side of the primer layer disposed opposite to the current collector and includes an active material. Additionally, the lithium secondary battery includes a positive electrode, a negative electrode or both, a separator disposed between the positive electrode and the negative electrode and an electrolyte. The structural stability and adhesion of the electrode is improved, a ratio of a binder in the active material layer is reduced and the internal resistance is reduced.
