Abstract: In order to solve the problems of over large thickness, short life, poor reliability of non-vacu
um 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 clement analysis software ANSYS, the impact of diferent thermal insulation materials on the actual
performance was analyzed and an optimal design by the actual test validation was proposed. The results indi
cate that the optimization design meets the design requirements, decreases the total thickness of thermal insula
tion structure by 37. 5%o 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 rel
able 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
