Definitions

  • a dry separator is disadvantageous because it causes an increase 1n internal resistance and lessened electrolytic Contact with the anode.
  • a dry mix is disadvantageous because it lowers the amount of electrical energy that the cell can deliver.
  • One further problem is that small amounts of oxygen from the air can enter the cell during venting.
  • the paper liner from which moisture has been lost, and which extends up into the air space, can provide a pathway through which oxygen can diffuse and thereby contact the inner surface of the anode. This can cause corrosion.
  • FIG. 10 shows a paper battery separator having a strip of plastic film attached at the top
  • the plastic films in AA sized cells having liners made in accordance with the invention were heat shrunk.
  • the plastic film employed was 3mil polyvinyl chloride film that was heat shrinkable in both directions.
  • a Master PHT-l ameless heat torch (purchased from Master Applicance Corporation, Racine, Wis. 53403) was employed to provide the heat. It had a nozzle shaped similarly to that shown in FIGS. 7 and 8, with an opening 1s-inch in diameter. The opening in the nozzle was positioned 12)s-inch above the top of the can.
  • At an air exit temperature of 980 F., and an air pressure of 2 p.s.i., 0.24 second residence time under the nozzle was suicient to effect the desired heat shrink operation.
