Abstract:
The present invention provides a fabricating method of a lithium electrode, a lithium electrode, and a lithium secondary battery including the same, the fabricating method including: a) forming an active material layer on one surface or active material layers on both surfaces of a current collector; b) forming a conductive fiber structure layer in a frame form on a surface of the active material layer; and c) pressing the current collector on which the conductive fiber structure layer in a frame form is formed. Since breakage of the active materials caused by pressing is prevented by the conductive fiber structure layer in a frame form, the present invention provides a lithium electrode capable of maintaining electronic conductivity between active material particles and having a long lifespan and high-rate charge and discharge characteristics.
