Safety is one of the most important factors for the sodiumsulfur
battery. Therefore, consideration must be given to
emergencies: fire, flood, dropping, etc.; as well as problems
occurring during normal operation: overloads, mishandling,
disorders, etc. This paper presents safety design concepts
and results of proof tests for safety items related to our
sodium-sulfur battery.
A sodium electrode design which minimizes the direct reaction
between the sodium and the sulfur, caused by betaalumina
tube breakage, secures the safety of the cells, and
suppresses temperature rise by an external short-circuit.
Fuses ensure the safety of the batteries having hundreds of
connected cells in case of an external or internal short-circuit.
The overcharge breakdown and short-circuit tests using cells
and batteries verified the above-mentioned safety features.
In addition, the forced internal burning, external flame, dropping,
and flood tests proved that our sodium-sulfur batteries
have sufficient safety features.
