MULTILAYER CONDUCTIVE FILM, CURRENT TAP USING ABOVE FILM, BATTERY AND BIPOLAR BATTERY Russian patent published in 2015 - IPC B32B27/18 B32B27/00 C08K3/04 C08L45/00 C08L65/00 H01M2/10 H01M10/525 H01M10/585 

FIELD: electricity.

SUBSTANCE: invention is related to a multilayer conductive film, current tap containing the above film, a battery with the current tap and a bipolar battery. The multilayer conductive film comprises layer 1 of a conductive material including polymer material 1 with an alicyclic structure in the main circuit and conductive particles 1, and layer 2 that includes a material resistant to the potential of a positive electrode. The material resistant to the potential of the positive electrode is a conductive material consisting of polymer material 2 resistant to the potential of the positive electrode and particles 2. Polymer material 2 has been selected out of the following group: aromatic polyimide, polyamide-imide, polyamide, polyethylene, polypropylene, silicone, polyphenylene simple ether, nylon, polybutylene therephthalate, polyphenylene sulphide, polyetheretherketon and polyester.

EFFECT: manufacturing of the multilayer conductive film with stability in the environment of the equilibrium potential at the negative electrode and stability in the environment of the equilibrium potential at the positive electrode having low electric resistance per unit area in the direction of thickness and superior barrier properties for the solvent of electrolytic solutions.
