摘要： The object of the present invention is to provide a carbon material having superior reversibility in lithium intercalation/de-intercalation reaction, and a non-aqueous secondary battery using the carbon material as an active material for its negative electrode, which has a high energy density and excellent rapid charging and discharging characteristics. Graphite powder having a maximum particle diameter of less than 100 µm and less than 20 % of rhombohedral structure in the crystalline structure is used as an active material for the negative electrode of the non-aqueous secondary battery. The graphite powder can be obtained by pulverising raw graphite with a jet mill and subsequently treating the powder at a temperature equal to or higher than 900 °C.

摘要： A lithium secondary battery suitable for use as a power source for a secondary battery using system such as an electric automobile, motor bicycle or portable equipment includes a negative electrode (17) composed of a carbon material including carbon particles carrying fine particles of a metal which forms an alloy with lithium. The carbon particles have a face-to-face dimension which is 3.354 to 3.369 Å and a crystal grain size in a C-axis direction which is equal to or greater than 300 Å. The metal forming an alloy with lithium has a particle size which is equal to or smaller than 1000 Å. With the use of the charge/discharge capacity of an alloy of the metal and lithium, a value exceeding the theoretical capacity 372 mAh/g of graphite can be obtained. The lithium secondary battery is capable of discharge with an output energy density equal to or higher than 350 W/kg.

摘要： A safe and controllable method of treating a secondary battery (15) having at least one component containing alkali metal, comprises the steps of opening the battery casing, and introducing a gas containing at least one of water vapour and alcohol vapour into a closed chamber (1) containing the battery thereby to form alkali metal hydroxide. To control hydrogen concentration, the rate of introduction of water and alcohol vapour may be varied. Apparatus for carrying out this method is also described.

摘要： The present invention provides a distributed secondary battery type power storage system capable of maintaining the soundness of the secondary battery and of efficient electric power charging and discharging operations. The secondary battery power storage system comprises a secondary battery connected to a load, a charge/discharge unit connectable to a power system and connected to the secondary battery, and a plurality of loads connected to the charge/discharge unit. A power receiving object is selected and a capacity is determined on the basis of information about the operating condition of the plurality of loads, and the surplus electric power remaining in the secondary battery after feeding electric power from the secondary battery to the load is fed to the selected power receiving object through the charge/discharge unit. The secondary battery power storage system is capable of maintaining the soundness of the secondary battery and of efficient charging and discharging operation.
