Abstract:
Glass-to-metal elements are widely used in military and civilian areas because of their excellent air tightness, sealing performance, mechanical strength and other comprehensive characteristics. There are some bad defects such as bubbles, holes, cracks in the interface of lithium battery insulator production. Repeated glass-to-metal seal experiments had been designed and made to analyze and observe the glass state, sealing properties, tensile strength and time of the insulators in this paper. As a result, we get the conclusion that multi-times glass-to-metal seal have great influence on sealing characteristics such as air tightness, tensile strength, etc. With the increasing times of glass-to-metal sealing, the comprehensive performance of the products get worse, and the max repeated seal times which can ensure the products performance have been discussed.
