摘要：A method for producing an electrochemical element having at least one lithium-

intercollating electrode and an organic electrolyte, at least one positive electrode, atleast one negative electrode and at least one separator are joined together to form anelement, with the separator being a porous matrix composed of at least about 60% byweight of a ceramic material A, which contains lithium ions, and a polymer as a bindingagent. The resulting element is then introduced into a housing and impregnated with aliquid organic electrolyte B, whose conductive salt contains lithium ions, so that the ionictotal conductivity of the separator is formed by adding the ion conductivities of A and Band the reciprocal of the specific contact resistance of the phase boundary between Aand B, and is then closed such that it is sealed. A copolymer composed of vinylidenefluoride and hexafluoropropylene is used as the binder polymer. Material A is a naturallyoccurring mineral.
