Abstract

In a lithium secondary battery comprising positive and negative electrodes each comprising at least an active material capable of occluding and releasing lithium ions, a binder and a current collector, and an electrolytic solution, the active material in the positive and/or negative electrode has been made conductive by coating its surface with a conductive agent and a binder, and affixed to the surface of the collector by a dry process. The lithium secondary battery is given a higher energy density and a higher output density and will find a wider range of application.
