Abstract
A cathode for a lithium secondary battery wherein the surface of the cathode of which a composition containing a cathode active material, a conductive substance and a binder is supported on a current collector, is coated with at least one ion-permeable resin selected from resins having a temperature of deflection under load (measured at 18.6 kg/cm.sup.2 load according to JIS K 7207) not lower than 100 .degree. C., provide a lithium secondary battery with high energy density having improved safety.
