  • Publication number: 20120003514
    Abstract: A non-aqueous electrolyte battery capable of making behavior of the battery calm at a time of battery abnormality to secure safety is provided. In a lithium-ion secondary battery 20, an electrode group 6 is accommodated in a cylindrical battery container 7 having a bottom. A positive electrode plate and a negative electrode plate are wound via separators W5 to form the electrode group 6. The positive electrode plate has an aluminum foil W1 as a positive electrode collector. A positive electrode mixture including a lithium transition metal complex oxide as a positive electrode active material is applied to both surfaces of the aluminum foil W1 to form a positive electrode mixture layer W2. A flame retardant layer W6 containing a flame retardant is formed at a surface of the positive electrode mixture layer W2. The negative electrode plate has a rolled copper foil W3 as a negative electrode collector.

  • Publication number: 20110195318
    Abstract: A lithium ion battery capable of maintaining for a long time fire resistance of a nonaqueous electrolytic solution at a time of battery abnormality to secure safety is provided. In the lithium ion battery, two kinds of organic solvent, EC and DEC, are used for mixed organic solvent which forms the nonaqueous electrolytic solution, and liquid flame retardant formed by phosphazene A having a boiling point closely to that of EC and phosphazene B having a boiling point closely to that of DEC is added to the electrolytic solution. At battery abnormality, when the battery temperature goes up due to internal short circuit of positive and negative electrodes caused by melting of separators to decompose each of EC and DEC, the phosphazene A and B, each having the boiling point closely to that of EC and DEC, decompose timely to function, thereby fire resistance of the electrolytic solution can be maintained for a long time to secure safety of the battery at the time of battery abnormality.

  • Publication number: 20110159329
    Abstract: A manganese non-aqueous electrolyte battery having safety at a time of battery abnormality and having a long life span is provided. A battery 20 has a cylindrical container 7 having a bottom. An electrode group 6 where a positive electrode plate that a spinel-related lithium manganese complex oxide is used as a positive electrode active material and a negative electrode plate that a carbon material is used as a negative electrode active material are wound via separators W5, is accommodated in the container 7. The electrode group 6 is infiltrated by an electrolytic solution in which LiBF4 is added as an electrolyte to organic solvent. Further, a phosphazene flame retardant is added at 10 wt % to the electrolytic solution. The electrolytic solution hardly catches fire at a time of battery abnormality and manganese elution can be prevented.

  • Patent number: 6854934
    Abstract: The invention provides a structure of a pile head joint portion and a pile had fitting tubular body which can absorb an execution error for constructing a pile leading to a problem in the case of precasting a board for supporting an upper structure in order to intend to shorten a process, and can improve a strength of the pile head joint portion. A precast board (5) is manufactured by embedding a pile head fitting tubular body (2) which is constituted by a side plate (23) forming a pile head fitting tubular body (2) and a closing plate (22) closing open one end of a tube body, and forms an opening portion (26) in another end open so as to freely fit a pile head. The pile and the board are integrally formed by fitting the pile head portion to the pile head fitting tubular body (2) after constructing the pile, and charging an injection material (4) into the pile head fitting tubular body (2).

  • Patent number: 5526777
    Abstract: An air path is provided in the main body of a chain saw so as to connect an air inlet port provided on the main body and a carburetor chamber of the internal combustion engine and also connected to a cooling fan chamber. For use under normal conditions, combustion air is taken from the air inlet port into the carburetor chamber. In case of a rainy or snowy day, the air inlet port is closed and combustion air is taken from the cooling chamber into the carburetor chamber, air control means is provided between the air path and the cooling fan chamber. This air control means generates stagnation of air flow in the cooling chamber in order to supply air into the carburetor chamber and prevent dust and the like from being taken into the air path.

  • Patent number: 5346785
    Abstract: A photochargeable air battery is disclosed possessing a negative electrode 22 which discharges by oxidation of metal material 22a, a positive electrode 21 comprising a oxygen catalyst, electrolyte 23 filling the inside of battery case 27 between negative electrode 22 and positive electrode 21, and battery case 27 housing positive electrode 21, negative electrode 22 and electrolyte 23 in addition to possessing light receptor 22a which injects light into negative electrode 22. As a result, discharging is performed by oxidation of metal material 22a comprising negative electrode 22, while charging is performed by reducing the oxidized metal material by means of irradiating light from light receptor 27a onto the metal material 22 which is oxidized by this discharging.

  • Patent number: 5310608
    Abstract: The temperature difference battery includes a solution 2 which contains redox ion couples having a temperature-dependent redox potential. A low-temperature (LT) electrode 1 and a high-temperature (HT) electrode 3 are disposed in the solution 2. A membrane film 6 impervious to the redox ion couples is disposed between the HT electrode 3 and the LT electrode 1. A LT power electrode 7 is disposed between the LT electrode 1 and the membrane film 6, and a HT power electrode 8 is disposed between the HT electrode 3 and the membrane film 6. When there is a temperature difference between the electrodes 1, 3, the redox potential of the ion couples change, and thermoelectric power is generated between the LT electrode 1 and the HT electrode 3, which is used to charge the battery. The concentration of the redox ion couples in the LT region and in the HT region increases as charging progresses, and the membrane 6 maintains the concentration difference thus storing the electrical power.

  • Patent number: 4728807
    Abstract: In a power source system for supplying a load with a load voltage and a load current, a plurality of power sources share the load at rates of load sharing and have negative resistance characteristics. When the power sources are connected together in series, the rates are determined by source voltages produced by the respective power sources which also produce d.c. currents. Each d.c. current increases with an increment of each rate so as to specify each negative resistance characteristic. A control circuit is included in each power source to control the d.c. current and may be a combination of a current detector (60a, 60b) and a resistor (56a, 56b). Alternatively, the rates are determined by source currents produced by the respective power sources which also produce d.c. voltages when the power sources are connected together in parallel. The d.c. voltages are controlled by control circuits to specify the negative resistance characteristics so that each d.c.
