Abstract
A flexible welding board for a battery pack, which is a polyester film with a laminated nickel alloy material. The polyester film with a co-extruded polymer adhesive includes a laminated nickel alloy thereon. The nickel alloy is subsequently silk screened with a pattern, and etched providing a flexible welding board for the welding of components of a battery pack, including the battery cells, electrical components and the electromechanical components which are spot-welded thereto. The entire process can be done robotically providing a battery pack which has electromechanical integrity between the battery cells, components, flexible welding board and the battery pack housing.

A battery pack comprising:
- a. a U-shaped polymer substrate;
- b. at least two strips of conductive material laminated by adhesive means to said substrate;
- c. at least one battery cell having positive and negative terminals at opposite ends disposed within said U-shaped substrate;
- and,
- d. welds securing one of said strips to the negative terminal and the other of said strips to the positive terminal.
A battery pack comprising:
- a. a U-shaped nonconducting substrate;
- b. a plurality of conductive strips adhesively secured to said nonconducting substrate;
- c. a plurality of battery cells each having positive and negative terminals at opposite ends disposed within said U-shaped substrate;
- and,
- d. welds securing said conductive strips to said terminals to electrically interconnect said cells.
