摘要： PURPOSE:To make it possible to manufacture metal contained fullerene with high efficiency by using an electrode available from the mixing and sintering of metals with easily graphitized carbon as a positive electrode and arc discharging the electrode inside a vacuum chamber and separating fullerene from the deposits. CONSTITUTION:A hole is bored in the center of a high purity graphite rod 3a and metal containing-carbon powder 3b is put into the hole, thereby producing a positive electrode 3 while the high purity graphite rod is used as a negative electrode. The positive and negative electrode 2 and 3 are installed in a chamber 1. Then, DC current is made to flow between the electrodes 2 and 3 from a DC power source 6 while the air in the chamber is being replaced with an inert gas. Then, arc discharging is produced between the electrodes 2 and 3 where soot called fullerene attaches to an inner wall 1a of the water-colled chamber. The removed soot is put into a quartz tube 8. While the inside the tube is being evacuated into high vacuum, the temperature is increased by using a heating device 9. A substance 10 sublimated from a filler 7 is cooled at the upper part of the quarts tube 8 and deposited. This construction makes it possible to provide metal lanthanum containing fullerene which is thermally stabilized.

摘要： PURPOSE:To form a carbon hyperfine particle by allowing a carbonaceous material containing the carbon hyperfine particle having a concentric spherical graphite structure to be stuck to a counter electrode. CONSTITUTION:A pair of the high purity graphite made counter electrodes 12, 13 several mm to 50mm in diameter is arranged at 0.2-1.5cm interval in a water cooled vacuum chamber 11 and is arc-discharged in the presence of an inert gas such as He of 10-500Torr after evacuating. Carbon of the structural material of the positive electrode 13 is vaporized and is made plasma to form a soot like adhered material 15 on the inside wall surface of the chamber 11. The adhered material 15 is a spherical carbonaceous material containing a fullerene expressed by Cn ((n) is 60, 70, 76, 84). A carbon added body 16 is deposited over 2-3cm from the tip of the negative electrode 12 by about 20% of the negative electrode volume on the negative electrode 12 at the same time as producing the fullerene. The carbon hyperfine particle of nm order size having the concentric spherical graphite structure is obtained by disentangling the carbon added body with an ultrasonic vibration device or the like.

摘要： PURPOSE:To provide a negative electrode material having a large quantity of Li addition by subjecting a carbon precurser hard to be turned into graphite to a processing in an inert gas atmosphere at a certain rate of flow or in an atmosphere with pressure, and laying the material one over another so that the contacting area with the atmosphere exceeds a certain level, CONSTITUTION:A carbon precurser is-subjected to a processing in an inert gas atmosphere at a rate of flow exceeding 0.1ml/min per gram or under 50kPa at a temp. over 600 deg.C. Therein laminating is made so that the precurser contacting area with the atmosphere exceeds 10cm per kg. Therein the conditions shall be met such that Ps in the Raman spectrum is selected as specified. If the material according to the constitution above is used, Li is not only added between C layers in the laminated structure part but added to minute voids in a disturbed C layer in the non-laminate part. This permits acquiring a quantity of addition which is much over the Li adding amount theoretical.

摘要： PURPOSE:To increase the discharge capacity and to improve the cycle life property by using a carbonaceous material made by carbonizing a petrolic pitch and regulating the morphologic parameter in a specific scope. CONSTITUTION:As a negative electrode, a carbonaceous material obtained by carbonizing a petrolic pitch, in which the surface interval of the (002) surface is 3.70 A or more, the true density is less than 1.70g/cm , and there is no heating peak more than 70 deg.C in the differential thermal analysis in the air current is used, while a substance including Li which is doped and dope-released to the negative electrode is used as a positive electrode, and a nonaqueous electrolyte is used. When the carbonaceous material used as the negative electrode has the surface interval of the (002) surface less than 3.70Angstrom , the discharge capacity is reduced and the cycle life is deteriorated. In the same manner, when its true density exceeds 1.70g/cm , the discharge capacity and the cycle life are deteriorated. And when the heating peak is at 700 deg.C or higher in the result of the differential thermal analysis, the battery property is deteriorated. Consequently, the cycle life property can be improved, and the discharge capacity can be increased.

摘要： PROBLEM TO BE SOLVED: To provide a battery having an excellent cycle characteristic by using a single metal or semi-metal element capable of forming an alloy with lithium, or its alloy or compound as a negative electrode active material.
SOLUTION: A pressing member 18 for pressing a negative electrode 14 in the opposite direction against a positive electrode is disposed between the negative electrode 14 and an armoring member. The pressing member 18 is partially cut and bent to thereby form pawls 18a. The pressing member 18 absorbs expansion of a negative active material layer 14a when it swells due to charging. When the negative active material layer 14a shrinks, the pressing member 18 prevents it from dropping off by applying a pressing force to the negative electrode 14 through a flat portion 18b. The pressing force of the pressing member 18 applied to the negative electrode 14 is preferably 0.02 kg/cm
2 or greater but less than 5 kg/cm
