Abstract:

In order to solve the problems of over large thickness, short life, poor reliability of non-vacuum thermal insulation structure for sodium-sulfur battery, the mathematical model was established by thermal conductivity theory of multi-level insulation layer structure, solid modeling and numerical simulation were done by finite element analysis software ANSYS, the impact of different thermal insulation materials on the actual performance was analyzed, and an optimal design by the actual test validation was proposed. The results indicate that the optimization design meets the design requirements, decreases the total thickness of thermal insulation structure by 37.5% by applying new thermal insulation materials, and then reduces the overall size and weight of the structure. Furthermore, the layout method of the thermal insulation materials arranged according to the material properties and thermal resistance was summarized, which ensures each material is safe and reliable under working conditions. Research results can provide technical references in design and optimization of the insulation structure for sodium-sulfur batteries and other devices in the future.
