Abstract: An adhesive tape that includes: a first adhesive layer defining an upper surface of the tape; a second adhesive layer defining a lower surface of the tape; and a reinforcement layer (or first and second reinforcement layers) and a thermally activated layer between the first adhesive layer and the second adhesive layer. The thermally activated layer is a thermoplastic polymer layer. The thermoplastic layer may be made of ethylene-vinyl acetate copolymer, modified polyolefin, ethylene acrylic acid copolymer, ethylene terpolymer, polyamide copolymer, poly(trans-1,4-isoprene), polyethylene oxide, or a combination thereof. Further, the thermoplastic layer may exhibit a melting point from 60° C. to 150° C. and may have a molecular weight from 1,000 to 1,000,000.

Abstract: An adhesive tape, and adhesive tape assembly, that includes: a first layer of adhesive (D), the layer (D) comprising at least one electrolyte; a second layer of adhesive (C), the layer (C) being electrically conductive; and an electrically conductive carrier layer (T), the carrier layer (T) disposed between the first layer (D) and the second layer (C). Further, the layers (D), (T), and (C) are disposed one above another such that none of the layers (D), (T), and (C) laterally protrudes beyond any of the other layers (D), (T), and (C). The adhesive tape assembly can further include a first substrate (A) that is electrically conductive, a second substrate (B) disposed on a face of the second layer (C) that is opposite the carrier layer (T), and wherein the second layer (C) laterally protrudes beyond the substrate (B) such that the layer (C) has an exposed face.
