BIPOLAR BATTERY ELECTRODE

摘要

A bipolar battery comprising a plurality of bipolar electrodes stacked together, each bipolar electrode comprising a conductive septum having positive and negative active material on opposite faces thereof. Each electrode has a nonconductive frame formed thereabout, and a mesa-like lattice which is integral with the frame, overlays the faces of the septum and is defined by an annular shoulder formed between the border of the lattice and the frame. Discrete spacer frames interjacent the electrode frames separate the electrodes from each other and define a region thereabout for retaining the battery's electrolyte. The faces of the spacer include an annular recess contiguous an inner rim thereof which receives, in nesting fashion, the mesa-like lattices for interlocking the several frames together.
