Abstract:
A bus bar for an electrolyte sheet is provided that includes a bus strip of electrically conductive material in contact with a side edge of the cell or cells in the electrolyte sheet, wherein the amount of material in shoulder portions of the bus strip decreases as the strip approaches end portions of the cell edge to reduce stress. Preferably, such material reduction is accomplished by tapering the shoulder portions of the bus strip. The tapered shape of the shoulders reduces the amount of electrical conductor needed to form the bus bar. The stress reducing bus bar also includes a lead which is orthogonally oriented with respect to the longitudinal axis of the side edge of the cell. The tapered shape of the shoulder portions of the bus strip, in combination with the orthogonally oriented lead, reduces stresses that would otherwise occur between the bus bar and the electrolyte sheet as a result of differences in the thermal coefficient of expansion. The specific shape of the taper in the shoulder portions is selected such that I 2 R losses are substantially minimized along the longitudinal axis of the bus strip.

Abstract:
The disclosure provides seals for devices that operate at elevated temperatures and have reactive metal vapors, such as lithium, sodium or magnesium. In some examples, such devices include energy storage devices that may be used within an electrical power grid or as part of a standalone system. The energy storage devices may be charged from an electricity production source for later discharge, such as when there is a demand for electrical energy consumption.

The service disconnect unit (16) also comprises a removable conductive member (50) configured to electrically connect the first portion (54) of the bus bar (52) to the second portion (56) of the bus bar (52).
Abstract:
An improved electrical connector system for joining an electrode and a terminal in an electrochemical cell is provided in which physical force is used to maintain the electrical contact. An extension member provided on the electrode is adapted to fit within a key-hole shaped opening provided in the terminal. A core member provided within the extension member is formed of a material having a higher thermal expansion than either the extension member or the terminal. Upon heating, the core member expands greater than both the terminal and the extension member, thereby physically forcing the extension member into electrical contact with the terminal.
