摘要： PURPOSE:To provide a sensor for detecting even a trace of sodium or sulfur leaked through a case housing containers containing fused sodium and sulfur individually. CONSTITUTION:At least the detection electrode 2a of a solid electrolytic sensor body 2 composed of a sodium ion conductor (e.g. a composite oxide salt of zirconate-silicate-sodium phosphate(Na1+xZr2SixP3-xO12) is disposed in a case housing containers containing fused sodium and sulfur individually in order to detect a trace of sodium or sulfur leaked from the container by means of a single sensor. A solid electrolytic sensor body is formed of a sodium ion conductor into a sheath and the inner and outer faces thereof are employed, respectively, as a reference electrode and a detection electrode. At least the forward end of the sheath is disposed in the case and a trace of sodium or sulfur leaked through the container is detected by means of a single sensor.

摘要： The present invention provides a space-saving and low-cost emergency power system, which can be installed on a narrow place having limited space and employs a battery that is long in service life and low in frequency of replacement. This emergency power system comprises a circuit having a DC load, a rectifier, and a battery, which are electrically connected to one another. This circuit is adapted so that normally, DC power is supplied from the rectifier to the DC load, and the battery is charged, and that in an emergency, such as a power failure, in which an outage of the rectifier occurs, electric power is automatically supplied from the battery to the DC load. In this system, a sodium sulfur battery is employed as the battery.

摘要： PROBLEM TO BE SOLVED: To provide a method of disposing a large number of used NaS batteries at once efficiently by a simple operation without bringing about a failure to a disposing device.
SOLUTION: The used sodium sulfur batteries are brought into discharge-ended states, metal sodium 5 remaining in a negative electrode is reduced, and a positive electrode is brought into a one-phase region composed ofa sodium polysulfide 6 in which sulfur does not exist, and then, supplied to a blast furnace or an incinerator and treated at 700°C or higher. At this time, one or both an outer circumference container 1 or a negative electrode lid 3 of the batteries are cut deeply or provided a hole before performing incineration treatment, and thereby, the efficiency of disposing can be further improved.

摘要： PROBLEM TO BE SOLVED: To provide a high power operation while maintaining high charge recovery performance by specifying the temperatures of a sodium-sulfur battery at starting a discharging step, at stating a charging step and through the charging step. SOLUTION: In a sodium-sulfur battery in which charging steps and discharging steps are repeated with resting steps therebetween, a battery system is operated so that the temperature of the battery at starting a discharging step can be 240-300 deg.C, the temperature of the battery at starting a charging step be 260-380 deg.C and the temperature of the battery through the charging step be kept at 260 deg.C or higher. A heating means and a control means to adjust its operation corresponding to the temperature of the battery are preferably used. It is desirable that set temperatures are 260-380 deg.C at finishing the discharging step and 240-300 deg.C at finishing the charging step or at the time when charged voltage arrives at a preset value in the charging step. In this way, the corrosion and deterioration of battery structural members are prevented, resulting in long-time operation.

摘要： PURPOSE: To reduce contact resistance between a sodium-sulfur battery and a positive electrode container when the battery is stored in a positive electrode chamber and to facilitate movement of sodium ions so as to promote charging reaction and to accomplish reduction in battery resistance and improvement in a charging recovery rate. CONSTITUTION: Flameproof processing of a felt 7 is carried out by heating the felt 7, which is formed of flameproof fiber made of polyacrylonitrile fiber, at 200 deg.C. Needle punching is carried out in the felt 7 so as to protrude fiber 15 in the felt 7 from the side face of the felt 7, and consequently, protruding fiber is formed. When the felt 7, in which graphitization is carried by burning at approximately 2000 deg.C, is stored inside a positive electrode chamber 6 of a battery, the protruding fiber is brought into contact with a positive electrode container 1 and contact resistant between the battery and the positive electrode container 1 is reduced, while charging reaction is smoothly performed.
