- - The low-temperature co-joining between alpha alumina - beta alumina and alpha alumina - metal in Sodium-nickel chloride and Sodium-sulfur battery

摘要

The present invention relates to low temperature simultaneous bonding of alpha-alumina and beta-alumina, and alpha-alumina and metal in a sodium-nickel chloride battery or a sodium-sulfur battery. According to an embodiment of the present invention, the low temperature simultaneous bonding of the alpha-alumina and the beta-alumina, and the alpha-alumina and the metal in the sodium-nickel chloride battery or the sodium-sulfur battery comprises: a step of performing acid treatment on surfaces of the alpha-alumina and the beta-alumina; a step of slurrying a bonding agent; and a step of bonding the alpha-alumina and the beta-alumina in an argon atmosphere. The present invention provides a simplified bonding process; and reduces bonding manufacturing costs.
