極室Ｒ２に区画形成されている。[Prior Art] As shown in FIG. 4 as a conventional sodium-sulfur battery, an upper portion of a bottomed cylindrical anode container 1 containing a porous conductive material M impregnated with molten sulfur S as an anode active material. On the other hand, the insulating ring 2 made of α-alumina is fixed, the cathode container 3 is fixed on the upper part of the insulating ring 2, and sodium ions Na + are selectively applied to the inner peripheral surface of the insulating ring 2. There has been a solid electrolyte tube 4 having a bottomed cylindrical solid electrolyte tube 4 made of polycrystalline beta-alumina extending downward and having a function of permeating the upper outer peripheral surface thereof. In addition, the inside of the battery is impregnated with the molten sulfur S by the solid electrolyte tube 4 and the conductive material M
Is partitioned into an anode chamber R1 for storing sodium and a cathode chamber R2 for storing sodium Na.

ウムイオンＮａ＋となって固体電解質管４を透過して陽
極室Ｒ１内の硫黄Ｓと次のように反応し、多硫化ナトリ
ウムを生成する。At the time of discharge, sodium becomes sodium ions Na + from the cathode chamber R2, passes through the solid electrolyte tube 4, and reacts with the sulfur S in the anode chamber R1 as follows to generate sodium polysulfide.
２Ｎａ＋Ｘｓ→Ｎａ２Ｓｘ 又、充電時には放電時とは逆の反応が起こり、ナトリウ
ムＮａ及び硫黄Ｓが生成される。2Na + Xs → Na 2 Sx Further, during charging, a reaction opposite to that during discharging occurs, and sodium Na and sulfur S are produced.

部的に硫黄に覆われた場合には、覆われていない部分へ
電流が集中し固体電解質管４の破壊につながる。Na 2 Sx → xS + 2e − + 2Na + Therefore, the generation of sulfur during charging occurs at the interface between the anode conductive material M which is an electron conductor and sodium polysulfide Na 2 Sx. When the anode conductive material M is in contact with the solid electrolyte tube 4, sulfur adheres to the surface of the solid electrolyte tube 4. When the surface of the solid electrolyte tube 4 is completely covered with sulfur due to this sulfur, the resistance rapidly increases and it becomes impossible to continue charging, and when it is locally covered with sulfur, current flows to the uncovered portion. Concentrate and lead to the destruction of the solid electrolyte tube 4.

(Japanese Patent Publication No. 59-10539) And, at the time of charging, the sodium polysulfide (Na 2
S 3 , Na 2 S 5 ) is kept in a wet state, and Na + ions are always uniformly present in the vicinity of the solid electrolyte tube 4 to prevent local sulfur adhesion to the surface of the solid electrolyte tube and eliminate its damage. There is.

た。[Problems to be Solved by the Invention] However, in the conventional sodium-sulfur battery, it is difficult to form a thin porous insulator, and therefore, it is difficult to form a porous insulator on the surface of the solid electrolyte tube. Since the thickness of sodium sulfide could not be reduced, the resistance could not be reduced and the charge / discharge efficiency could not be improved. Insulator 1
When 1 was thinned to about 200 μm, it was very difficult to set it evenly inside the battery, glass fibers were broken, which was a problem in production, and it was difficult to control the characteristics.

１図〜第３図に基づいて説明する。[Embodiment] An embodiment in which a sodium-sulfur battery is embodied will be described below with reference to FIGS. 1 to 3.

Further, the lower end portion of the cathode container 3 having a cylindrical shape with a lid is fixed to the upper surface of the insulating ring 2 by thermocompression bonding. On the inner peripheral surface of the insulating ring 2, the upper end outer peripheral surface of the solid electrolyte tube 4 having a bottomed tubular shape made of β ″ -alumina is adhered and fixed by glass or the like.

Further, metallic sodium Na as a cathode active material is stored in the cathode chamber R2 formed between the cathode container 3 and the solid electrolyte tube 4. In addition, 5 is an anode terminal and 6 is a cathode terminal.
次に本発明の要旨について第１図により説明する。Next, the gist of the present invention will be described with reference to FIG.
前記固体電解質管４の外表面には、粒径が１０〜５００

粒子７〜７を粒径変形させることなく、厚さほぼ２０〜
１０００μｍに塗布してセラミク粒子高抵抗層８を形成
している。前記セラミック粒子高抵抗層８の厚さが厚す
ぎると充放電時の抵抗損が大きくなり、電池効率が低下
するし、薄すぎると充放電時に硫黄が境界に飽和してし
まい、充填が早期に終了するとともに、粒子高抵抗層８
の部位に厚さむらが生じ易くなって特性が不均一となる
ので前述した範囲が望ましい。特に望ましい粒径範囲は
３０〜３００μｍである。この理由は粒径が小さすぎる
と高抵抗層の多孔度が小さくなり、ナトリウムＮａ＋等
の活物質の移動が妨げられるし粒径が大きくなると均一
な厚さに形成することが難しくなるからである。The outer surface of the solid electrolyte tube 4 has a particle size of 10 to 500.
The thickness of the ceramic particles 7 to 7 having a resistance to sulfur and sodium polysulfide such as .mu.m of .alpha.-alumina, zirconia or .beta.-alumina is about 20
It is applied to a thickness of 1000 μm to form a ceramic particle high resistance layer 8. If the thickness of the ceramic particle high resistance layer 8 is too thick, the resistance loss at the time of charging / discharging becomes large and the battery efficiency is lowered, and if it is too thin, the sulfur is saturated at the boundary at the time of charging / discharging, and the filling becomes early. Upon completion, the particle high resistance layer 8
The above-mentioned range is desirable because unevenness in thickness is apt to occur in the area and the characteristics become non-uniform. A particularly desirable particle size range is 30 to 300 μm. The reason for this is that if the particle size is too small, the porosity of the high resistance layer becomes small, the movement of the active material such as sodium Na + is hindered, and if the particle size becomes large, it becomes difficult to form a uniform thickness. is there.

７が散布され固着されている。As a method of forming the ceramic particle high resistance layer 8, molten sulfur S or sodium polycarbide Na 2 Sx is applied to the surface 4 a of the solid electrolyte tube 4, and the surface of the sulfur S or sodium polysulfide Na 2 Sx is ceramic. There is a method of spraying particles 7 to 7 and fixing them. Further, on the inner peripheral surface of the anode conductive material M impregnated with the molten sulfur S, the ceramic particles 7-

層８を形成したので、製造が容易になる。Now, according to the present invention, the ceramic particles 7 to 7 are dispersed to a uniform thickness on the surface 4a of the solid electrolyte tube 4 or the inner surface of the anode conductive material M impregnated with sulfur S to form the ceramic particle high resistance layer 8. Therefore, manufacturing becomes easy.

る。Further, since the thickness of the ceramic particle high resistance layer 8 can be reduced to an appropriate range, the charge and discharge efficiency can be improved by lowering the battery resistance, and the high resistance layer 8 which is porous in terms of capacity is also completed when charging is completed. Since the amount of sodium polysulfide remaining inside can be reduced, the charge amount increases.
