Abstract

A bipolar battery assembly of the consumable metal anode type is described. Contact between internal battery elements is now enhanced by air assisted, internally exerted compressive force. Battery elements are constructed in modular manner that assists in the ease of battery assembly and disassembly. Furthermore, ease of anode replenishment is maintained. A multitude of individual cells can now be joined together in an efficient bipolar assembly cell stack for augmented electrical energy generation. In addition to being bipolar, the battery is of rugged construction, providing for dependable, long-life operation that is desirably maintenance-free.
