Abstract

A method for recovering sodium from a sodium-sulfur battery of the present invention includes a reaction step of injecting a treatment liquid toward the sodium housed in a sodium-housing component in the battery container and causing the sodium to react with the treatment liquid so as to generate a reaction liquid; and a circulation step of generating the treatment liquid by adjusting the concentration and liquid temperature of the reaction liquid, and, in the reaction step, while the entire amount of the sodium is reacted with the treatment liquid, the treatment liquid is continuously injected toward the sodium.
