ABSTRACT:
A pressure vessel construction for a rechargeable metal oxide hydrogen battery. The pressure vessel includes a generally cylindrical shell, the ends of which are enclosed by dome shaped heads. A metal fitting is mounted within an opening in at least one head and the electrical leads connected to the battery cell are sealed within an opening in the fitting. The vessel includes a flexible inner liner of material which is impervious to the passage of hydrogen gas and an outer layer of fiber reinforced resin which is capable of withstanding the internal pressure generated by the hydrogen. The inner liner can consist of a plurality of wrappings of thin plastic film, such as polyvinylidene chloride, or alternately the inner liner can consist of thin metal sections having overlapping edge portions sealed by resilient elastomeric sealing strips which permit expansion and contraction of the metal liner under varying internal pressure conditions, without causing major tensile stress in the metal.
