INSERT METALS FOR THERMAL COMPRESSION BONDING FOR SODIUM-SULFUR RECHARGEABLE BATTERY

摘要

An insert metal for thermal compression bonding for a sodium-sulfur battery is provided. According to the present invention, the insert metal for thermal compression bonding for a sodium-sulfur battery is inserted in a bonding surface to bond, by thermal compression bonding (TCB), a metal collar installed in an alpha-alumina insulation ring and a cathode container of the sodium-sulfur battery. The insert metal has an alloy composition containing Al, 0.1-10 wt% Mg, and 0.1-5 wt% Si.
