Abstract:
A method of creating a gas restrictive interface in a battery between at least one battery strap plate of a cell block and at least one battery case partition of a battery case, comprising:forming a notch in an upper portion of the at least one battery case partition; disposing a sealing material on at least a portion of the notch; inserting the cell block within the battery case so that the at least one case partition separates cells of the cell block, the at least one case partition extending above a top surface of the at least one battery plate strap which electrically connects one cell to a next adjacent cell; forming a first seal between the at least battery plate strap and the notch by disposing the at least one battery strap plate in a heated state across the sealing material disposed in the notch; and attaching a battery case lid to the battery case, the battery case lid having at least one partition tab which is complementary to the notch and received therein when the battery case lid is attached to the battery case, wherein a bottom surface of the at least one partition tab includes the sealing material disposed thereon so that a second seal results between a top surface of the heated at least one battery strap plate and the bottom surface of the at least one partition.
