BATTERY Cell Electrolyte Sealing Tape, single sided acrylic adhesive tape with high chemical resistance and high adhesion used for a battery of portable electronic equipment. Polyconics polyimide tapes are dimensionally stable at high temperatures so they remaining intact during the numerous temperature cycles batteries experience. The tapes also insulate the batteries from external high temperature heat sources within the device. In addition, the halogen free (including bromine and chlorine free), flame retardant tapes prevent the propagation of fire. Polyonics tapes include both single coated tapes for masking and double coated tapes for bonding and are REACH and RoHS compliant. An electrolyte is a substance that produces an electrically conducting solution when dissolved in a polar solvent, such as water. The dissolved electrolyte separates into cations and anions, which disperse uniformly through the solvent. Electrically, such a solution is neutral. If an electric potential is applied to such a solution, the cations of the solution are drawn to the electrode that has an abundance of electrons, while the anions are drawn to the electrode that has a deficit of electrons. The movement of anions and cations in opposite directions within the solution amounts to a current. This includes most soluble salts, acids, and bases. Some gases, such as hydrogen chloride, under conditions of high temperature or low pressure can also function as electrolytes. Electrolyte solutions can also result from the dissolution of some biological (e.g., DNA, polypeptides) and synthetic polymers (e.g., polystyrene sulfonate), termed “polyelectrolytes”, which contain charged functional groups.
