Bitumen is sealing of battery

The battery seal set forth in solves many of the processing problems as described above. However, as with cells incorporating bitumen and polyamides in the seal area, extreme care must be taken to confine the organosilane resin of the van Lier patent to the immediate area of the seal, otherwise the electrical operation of the cell will be adversely affected by the introduction of a non-conductive layer between the electrode and current collector.
