SODIUM-SULFUR RECHARGEABLE BATTERY

摘要

Provided is a sodium sulfur battery that is capable of increasing battery efficiency and output by increasing the amount of sodium filled in an electrolyte tube to be proportional to the amount of sulfur. The present invention includes: a positive electrode container that accommodates sulfur; a negative electrode container that accommodates sodium; an electrolyte tube that is disposed between the positive electrode container and the negative electrode container, and allows only a sodium ion to be selectively moved; and an insulator that is disposed between the negative electrode container and the positive electrode container, and insulates the negative electrode container and the positive electrode container. The length of the width of the electrolyte tube is relatively greater than the length of the thickness of the electrolyte tube.
