Abstract
Improvements in the end block design for zinc/bromine batteries include modification of the end block configuration which previously has included rigid resin covers and end block plates with a honeycomb structure sandwiched therebetween. Such prior structures were used adjacent to terminal electrode frames. In the present invention, the terminal electrodes are preferably contained within the end plate, thereby eliminating two components used in prior zinc/bromine battery design and the end block itself is formed from two components by building a rib structure into the plate and cover and welding the two components together to join the ribs and form an integral and structurally sound unit. The end block configuration could be used for bipolar lead-acid batteries or other types of flowing or non-flowing batteries or capacitors.
