2 / 16 page 2 If the cathode and anode come in contact with each other, a very active chemical reaction would occur. A barrier must be between the two. A paper separator soaked with an electrolyte that promotes ionic or electrolytic conductivity is used as this barrier. The anode portion is a gel made up of zinc powder and several other materials. The anode is then inserted into the steel can against the paper separator. To insure a long shelf life, the battery must be sealed. The seal is made of a brass nail (which acts as the current collector), a plastic gasket, a steel washer and metal endcap. The four items are preassembled and inserted into the middle of our steel can up against the indentation (which was formed earlier). A top plate is welded to the other end of the can to provide the positive polarity safety feature. The batteries are then stored, given another voltage test and a decorative,insulating outer label is applied. Rayovac has further developed the alkaline system and introduced Rechargeable AlkalineTM Batteries. (Refer to OEM Designer's Guide OEM-150) Zinc Chloride Heavy duty zinc chloride batteries are the result of technological advances in zinc carbon battery manufacturing. The type and purity of the mix ingredients is why a zinc chloride battery lasts up to twice as long as the older zinc carbon formulations. (Diagram 2) A powdery mix serves as the cathode component of the zinc chloride battery. The mix is made of manganese dioxide (the active ingredient), carbon black (for electrical conductivity and moisture absorption), and zinc chloride electrolyte (which assists the chemical reaction). The anode portion of a zinc chloride battery is a pure zinc can. Besides acting as the anode, the zinc can also serves as a container for the remaining battery components. A paper separator and bottom cup is used to keep the components from coming in contact with each other.
