Abstract
Abstract A process of making laminar electrical cells and batteries each having an end terminal comprising a thin sheet of metal, in which an elongated web is made by adhering the end terminals to a sheet of dimensionally stable thermal insulating material in a spaced rectangular array of rows and columns. The process of forming pockets in the end terminals and registering the pocketed terminals on a second web carrying a spaced rectangular array of battery components comprising the steps of forming index perforations in each terminal, deforming the terminals to provide pockets therein, and joining the terminal web and the second web with the aid of the index perforations.
