A method of joining two metal members to a graphite member to form a structure having a low transition resistance is described. The method includes the steps of providing a plurality of openings in the graphite member, interposing the graphite member between the two metal members and positioning the metal members to cover the openings in the graphite member, and resistance spot welding the metal members to the graphite member at the openings in the graphite member. This method is advantageous in forming a bus-bar connection between a pair of opposite polarity graphite electrodes in an electrochemical cell stack, such as a zinc-chloride battery. In this particular application, it is preferred that titanium be used for the metal members. |
