HD1837 is a PAA-class cathode edge adhesive that uses low-polarity acrylate resin and can be blended with ceramic materials to coat the edge of the cathode to improve battery safety and achieve high adhesion between the aluminum foil and the separator. Compared to PVdF, this material has better flexibility properties.
