Conductive material E 30-90 wt% conductive particles, 5-70 wt% acrylic elastomer and 0.1-5 wt.% of additives. Conductive material F is a conductive film. The conductive film is a conductive copper foil, double conductive copper foil tape, conductive gauze, double-guided conductive yarn tape, graphene sheets, graphite paper and/or carbon fiber braided layers. The conductive particles are metal particles, metal fiber, alloy particles, low melting point alloys, carbon material, graphite powder, graphite nanosheets, graphene, carbon nanotubes and/or ceramic materials with surface conductive coatings.
