    • The present application provides for metal rings and ceramic collars for active brazing in sodium-based thermal batteries. The metal rings may be outer and inner Ni rings configured for sealing to an alpha-alumina collar via active brazing for use in NaMx cells. The inner and outer Ni metal rings may be sealed to differing portions of the alpha-alumina collar. The portions of the outer and inner Ni rings active brazed to the alpha-alumina collar may define a tapered thickness that reduces internal stresses at the active brazed joints resulting from differing coefficients of thermal expansion between the Ni metal rings and the alpha-alumina collar. The portions of the outer and inner Ni rings and alpha-alumina collar sealed by active brazing, and thereby the active braze joints themselves, may be oriented to control or dictate the stresses on the joints during use.
    • 本申请提供了用于钠基热电池中的活性钎焊的金属环和陶瓷套圈。 金属环可以是外部和内部Ni环,其被配置用于通过用于NaMx电池的活性钎焊密封到α-氧化铝环。 内部和外部Ni金属环可以密封到α-氧化铝轴环的不同部分。 活性钎焊到α-氧化铝轴环的外部和内部Ni环的部分可以限定锥形厚度,其减小由于Ni金属环和α-氧化铝环之间的不同热膨胀系数而导致的活性钎焊接头处的内部应力。 通过主动钎焊密封的外部和内部Ni环和α-氧化铝环的部分以及由此的活性钎焊接头本身可以被定向以控制或指示使用期间接头处的应力。

    • The present application provides configurations, components, assemblies and methods for sealing cells of sodium-based thermal batteries, such as NaMx cells, without a bridge member. In some embodimentsl the cells may include an electrically conductive case directly hermetically sealed to an electrically insulating ceramic collar of the cell to hermetically seal an anodic chamber of the cell. In some embodiments the ceramic collar and an electrolyte separator tube may be a cosintered one-piece member. In some embodiments the case and the ceramic collar and separator tube may form a hermetically sealed anodic chamber therebetween. In some embodiments the separator tube may define, at least in part, a cathodic chamber therein. In some embodiments the cells may include a current collector hermetically sealed to the ceramic collar, and a cap member hermetically sealed to the current collector to hermetically seal the cathodic chamber of the cell.
    • 本申请提供了用于密封钠基热电池如NaMx电池的电池的配置,组件,组件和方法,而没有桥接元件。 在一些实施例1中,电池可以包括直接气密地密封到电池的电绝缘陶瓷套环的导电壳体,以气密地密封电池的阳极室。 在一些实施例中,陶瓷套环和电解质分离器管可以是烧结成一体的构件。 在一些实施例中,壳体和陶瓷套环和分离器管可在其间形成气密密封的阳极室。 在一些实施例中,分离器管可以至少部分地限定其中的阴极室。 在一些实施例中,电池可以包括密封到陶瓷轴环的集流器,以及气密地密封到集电器以密封电池的阴极室的盖构件。
