The temperature increasing method for a sodium-sulfur battery, which involves three or more temperature gradients, inflection points at 90 ± 5°C and 150 ± 5°C at which the temperature gradient changes, and the temperature gradient in the section between 90 ± 5°C and 150 ± 5°C is 5°C/h or lower, is capable of increasing the temperature of the sodium-sulfur battery quickly without affecting the quality of the sodium-sulfur battery. |
