The demand for increased performance from batteries in missiles, space applications and torpedo propulsion has generated extensive battery development over the years. Dramatic improvements in the specific energy capability of the Silver Zinc System can be expected only through the development of new materials, novel approaches and/or new concepts in the design of the Silver Zinc batteries. One concept that Yardney is currently re-evaluating is bipolar construction. The major incentive for the use of bipolar cells in a pile configuration is the elimination of intercell connectors, other heavy current carrying structural elements and some of the cell containment features. This allows for substantial weight and size reduction, while increasing the specific power/energy density of the battery. Much of this work was originally developed by Yardney in the late 1960's to early 1970's.
