    Abstract: Provided is a pressure-sensitive adhesive tape for electrochemical devices according to the present invention. The adhesive tape is for use in electrochemical device production and includes a substrate and a pressure-sensitive adhesive layer. The adhesive layer is disposed on or over at least one side of the substrate and contains an acrylic polymer as a base polymer. The adhesive tape has a first and a second 180° peel adhesion strength. The first 180° peel adhesion strength is measured at 25° C. and a peeling speed of 300 mm/min after bonded to a SUS 304BA plate at a temperature of from 40° C. to below 150° C. The second 180° peel adhesion strength is measured at 25° C. and a peeling speed of 300 mm/min after bonded to a SUS 304BA plate at 25° C. The first 180° peel adhesion strength is twice or more as high as the second 180° peel adhesion strength.

    Abstract translation: 提供了根据本发明的用于电化学装置的压敏粘合带。 胶带用于电化学装置生产，包括基材和压敏粘合剂层。 粘合剂层设置在基材的至少一侧上或上方，并且含有作为基础聚合物的丙烯酸类聚合物。 胶带具有第一和第二180°剥离粘合强度。 在40℃至低于150℃的温度下，在SUS304BA板上粘合后，在25℃下测量第一180°剥离粘合强度，剥离速度为300mm / min。第二180°剥离 在25℃下，粘合强度为25℃，剥离速度为300mm / min。第一180°剥离粘合强度为第二180°剥离粘合力的两倍以上 强度。
