Embodiment Construction
[0019] refer to figure 1 , a bipolar metal hydride nickel sealed alkaline secondary battery, including a case 1, in which a first negative electrode 2, a first separator paper 3, a bipolar single electrode 4, a second Separator paper 9, first positive electrode 5. The first negative electrode 2 and the first positive electrode 5 have lead wires 7 drawn out from lead holes reserved in the case. The housing is sealed with a sealing ring 6 . Wherein the bipolar single electrode 4 (such as figure 2 As shown) the second negative electrode 10, the film 12 and the second positive electrode 11 are stacked in order from top to bottom, and the second negative electrode 10 and the second positive electrode 11 are welded and conducted with nickel strip 8 at the edge. The separator paper is made of polypropylene separator paper. Film can adopt common plastic film.
