Method for manufacturing of a galvanic element

The production of a galvanic cell with lithium (Li)-intercalated electrode(s) comprises combining an anode and a cathode and separator(s) with a porous matrix of not less than 60 wt.% ceramic material A containing Li ions and polymer binder; placing in a housing; impregnating with liquid organic electrolyte B with conductive salt containing Li ions, so that total ionic conductivity of separator is sum of ionic conductivities of A and B and reciprocal specific contact resistance of A/B phase boundary; and sealing housing tightly. An Independent claim is also included for a galvanic cells produced as above.
