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 ° C. and a mean particle size of from about 6 to about 20 &mgr;m, the amount of wax being between about 0.5 and about 2.5 mg/cm2 of electrode area.

Abstract: The temperature rise associated with the catalytic recombination of battery gases at the end of the charging process is converted into an electrical signal suitable for checking and controlling charging, in a temperature-sensitive component such as a commercially available NTC or PTC resistor coated with a PTFE-bound palladium-activated carbon mixture. An additional activated carbon layer protects the catalyst from poisoning by the stibine present in the battery gases.

Abstract: For continuous supply of expander material to the negative electrode of a lead storage battery, particularly a quinone derivative, this material is provided within an acid-resistant plastic vessel with an aperture toward the electrolyte, or in a chemically neutral matrix in tablet form.The size of the aperture or the porosity of the chemically neutral matrix so regulates the expander delivery that uniform supply is insured during at least a portion of the life span of the storage battery.

Abstract: The weight of the negative active mass is below 80% of the positive active mass.Preferably there is one more positive than negative plates.
