▎ 摘  要

NOVELTY - The system has an electrically conductive strip (10) formed on an electrically insulating polymer film (1). A tab forms a current collector (7) that is thermally sealed to the electrically conductive strip by a heat-fusible and electrically conductive polymer (11).The electrically insulating polymer film is formed as separator of an electrochemical cell. The electrically insulating polymer film is made of a monolayer or multilayer microporous polymer film based on polyolefin, preferably polypropylene and derivatives or/and polyethylene. The electrically conductive polymer is made of an elastomer of the polypropylene type and derivatives and/or polyethylene. A carbon-based electrically conductive filler is selected from carbon black, carbon fibers, carbon nanotubes, graphite, graphene and their derivatives, or a mixture of carbon compounds, or metal based aluminum, copper or nickel wires. USE - Electrochemical system for a metal-ion electrochemical accumulator (claimed). ADVANTAGE - The system realizes production of an electronically conductive junction between an instrumentation element integrated into a separator and external connection to packaging of the accumulator. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a metal-ion electrochemical accumulator. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic perspective view of an electrochemical system for a metal-ion electrochemical accumulator. 1Electrically insulating polymer film 7Current collector 9Instrumentation element 10Electrically conductive strip 11Heat-fusible and electrically conductive polymer
