SODIUM-SULFUR RECHARGEABLE BATTERY

摘要

PURPOSE: A natrium-sulfur battery is provided to minimize interference of welding by improving the cathode connection terminal structure and to easily implement wiring connection with the cathode. CONSTITUTION: A natrium-sulfur battery (100) includes an anode instrument (14) for sulfur accommodation, a cathode container (12) for sodium accommodation, an electrolyte pipe (10) installed between the anode instrument and the cathode container to selectively transfer only sodium ions, an insulator (16) insulating the cathode container and the anode instrument, a negative plate (20) is connected at the upper part of the cathode container to govern electrons and a connection terminal (30) formed on the negative plate. The connection terminal includes one or more screw taps (32) formed on the negative plate.
