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： PURPOSE:To provide a nonaqueous electrolytic secondary battery with high charging/discharging efficiency, high cycle performance, and high quick-charging capability by adding a fluorine family surfactant to a nonaqueous electrolyte of the nonaqueous electrolytic secondary battery. CONSTITUTION:A disk-shaped positive electrode 2 is put into a positive can 5, and a negative electrode 1 is placed on the positive electrode 2 through a porous separator 3. A negative can 4 is put on the negative electrode 1, and the negative can 4 and the positive can 5 are sealed through a sealing gasket 6. A fluorine family surfactant is used as a surfactant adding to a nonaqueous electrolyte. The fluorine family surfactant obtained by replacing part or whole of hydrogen atoms in hydrophobic groups of a hydrocarbon family surfactant with fluorine atoms remarkably decreases the surface tention of the electrolyte, and has high chemical resistance and heat resistance. The content of the surfactant in the nonaqueous electrolyte is preferably 10ppm to 1wt%. Deposition/ dissolution reaction of lithium uniformly proceeds on the surface of the negative electrode.
