Abstract: An electrochemical cell is presented. The cell includes a housing having an interior surface defining a volume, and an elongated, ion-conducting separator disposed in the volume. The separator usually extends in a vertical direction relative to a base of the housing, so as to define a height dimension of the cell. The separator has a first circumferential surface defining a portion of a first compartment. The cell further includes a shim structure disposed generally parallel to the first circumferential surface of the separator between the interior surface and the first circumferential surface of the separator. The structure includes at least two shims, a first shim and a second shim, that substantially overlap each other. An energy storage device including such an electrochemical cell is also provided.

Abstract: 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.

Abstract translation: 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。
