Abstract
A battery (10) comprises a cylindrical pressure vessel (30) having domed ends and an internal impermeable membrane (36) extending transversely to a cylindrical axis (38) of the pressure vessel (30). The impermeable membrane (36) divides the pressure vessel (30) into two compartments (32, 34) of equal size, shape, and volume, and hermetically seals the two compartments (32, 34) against mass flow therebetween. In particular, the membrane (36) prevents the migration of electrolyte between the storage elements located in the two compartments (32, 34). The battery (10) further includes a plurality of plate sets (12) for storing electrical energy, each plate set (12) having a nickel positive electrode (14), a hydrogen negative electrode (16), a separator (18) between the positive electrode (14) and the negative electrode (16), a gas screen (26), and an electrolyte. The active plate sets (12) are arranged with at least two active plate sets (12) in the first compartment (32) electrically connected in parallel to form a first cell stack (40), and at least two active plate sets (12) in the second compartment (32) electrically connected in parallel to form a second cell stack (42). The activ…
