Abstract
An element stack and a method of making same is provided in which assembling a relatively large number of relatively small electrode plates into an element stack is facilitated by positioning a first set of electrode plates onto a strip of separator material in pre-selected locations and then affixing such plates to the strip. The resulting product may then be readily processed into the element stack by insertion of a second set of electrode plates of opposite polarity to the first set and then folding the separator in accordion fashion. The assembly method is amenable to automation and the resulting cell element stack may be handled as a unit thereby facilitating battery assembly.
