Multi-tube type sodium and sulfur battery

The invention provides a multi-tube type sodium and sulfur battery. The multi-tube type sodium and sulfur battery comprises an anode, an anode outer casing, a cathode and a cathode outer casing, wherein the cathode extends into the anode through a plurality of composite cathode tubes which are distributed in an array way; the composite cathode tubes are arranged in a co-cathode way; each composite cathode tube comprises an inner porous metal layer and a solid electrolyte layer, and each solid electrolyte layer is attached to the outer layer and is supported by the corresponding porous metal layer. The multi-tube type sodium and sulfur battery has the advantages that by designing the porous metal layer, the problem of easiness in cracking of the ceramic tube of the tube type sodium and sulfur battery is solved, and the battery property and the safety class are improved; by adsorbing the ion liquid in the porous metal layer of each composite cathode tube, the working temperature of the battery is decreased, the
