Title: Method for producing a secondary lithium cell comprising a heat-sensitive protective mechanism

Abstract

A method for producing a secondary lithium cell which has at least one lithium-cycling negative electrode, at least one lithium-intercalating positive electrode, at least one separator disposed between the positive and the negative electrode, and a nonaqueous lithium ion-conducting electrolyte. The method is carried out by the electrodes and/or the separator being coated, by means of electrostatic powder coating, with wax particles which are insoluble in the electrolyte and have a melting temperature of from about 50 to about 150 .degree. C. and a mean particle size of from about 6 to about 20 .mu.m, the amount of wax being between about 0.5 and about 2.5 mg/cm.sup.2 of electrode area.
