Abstract: A method for manufacturing electrode-separator assemblies for galvanic elements includes hot-lamination at temperatures close to the melting point or softening point of at least a portion of the surface of an electrode or separator to a separator or electrode, respectively.

Abstract: A method for producing electrode sheets for electrochemical elements which contain at least one lithium-intercalating electrode which is composed of a mixture of at least two copolymerized fluorized polymers in whose polymer matrix electrochemically active materials which are insoluble in the polymer are finely dispersed, the fluorized polymers are, having being dissolved as a solvent, mixed with electrochemically active materials, the resulting pasty substance is extruded to form a sheet and then laminated with a polyolefin separator, which is provided with a mixture of the two polymers, PVDF-HFP copolymers in each case being used as the polymer, and the proportion of HFP being less than about 8 percent by weight.

Abstract: A method for producing a separator/electrode assembly for electrochemical elements which contain at least one lithium-intercalating electrode finely dispersing insoluble active materials in a polymer matrix to form a paste; directly applying the paste to a porous separator material or to a layer composed of solid ion conductors; and drying the paste.

Abstract: A method for monitoring the operational reliability of rechargeable lithium cells including measuring the cell voltage and cell temperature, the cell is discharged if a predetermined cell limit voltage (UG) and a predetermined ambient limit temperature TG are exceeded at the same time, until a predetermined lower voltage level or a predetermined lower ambient temperature is reached. A circuit for carrying out the method has a first threshold value switch which responds when a predetermined upper limit voltage (UG) is exceeded in the cell, and a second threshold value switch (C) which responds when a predetermined ambient temperature limit (TG) is exceeded, and has a logic circuit (E) which connects (G) the cell to a load when the first and second threshold value switches respond at the same time, wherein both threshold value switches (C, D) are configured such that they trip when a lower cell voltage or a lower ambient temperature is reached.
