摘要： PROBLEM TO BE SOLVED: To enlarge lithium storage/discharging capacity by constituting a negative electrode so as to contain graphite powder rhombohedral graphite structure below a specific percent. SOLUTION: Either of natural graphite or artificial graphite may be used for a material (raw graphite) of graphite powder, and especially scale-shaped natural graphite is preferable. A jet mill is used for a machine pulverizing the raw graphite into the grain size 100 μm or less. This machine can reduce the generated quantity of amorphous carbon. The pulverized raw graphite (raw powder) contains rhombohedral structure graphite by 30%. The graphite powder obtained by pulverization is treated by an acidic solution containing at least one of sulfuric acid, nitric acid, perchloric acid, phosphoric acid, and hydrofluororic acid. Secondly, the compound is washed, neutralized, and dried to remove anions in the acidic solution to be obtain a desired graphite powder. In this case, the presence rates of the rhombohedral structure and the hexagonal structure are set to 20% or less and 80% or more respectively.

摘要： PROBLEM TO BE SOLVED: To provide a lithium secondary battery having high capacity and long life. SOLUTION: Graphite powders, in which the percentage of edge surfaces is increased so that lithium is easily intercalated, are used as a negative active material. Graphite crystals are specified by the degree of anisotropy of the graphite crystals which appears on an ESR pattern, and the percentage of the edge surfaces is specified by the intensity ratio of the two Raman peaks of the graphite material. This constitution provides a secondary battery having high capacity and long cycle life.

摘要： PURPOSE:To obtain a spectroscope, in which light loss is reduced and polarization modulation is performed effectively and of which operation is facilitated, by using a step-scan type coherent infrared spectroscope, and rotating a polarizer to take out the polarization modulated infrared rays. CONSTITUTION:Infrared rays generated from a light source 1 pass through a wire-grid type infrared polarizer 2, which is rotated at a constant revolutional speed, and is polarization modulated, and enter the sample 3, of which a solid substrate is coated with a thin film. Infrared rays reflected by the sample 3 pass through a coherent optical system, which consists of a beam splitter 4, a fixed mirror 5, and a movable mirror 6 to be moved intermittently step by step, and are detected by a detector 7. Since the detector 7 is operated under the ordinary temperature condition, a pyroelectric detector, of which operation is facilitated and which has the excellent linear responsiveness, can be used. Fourier transform is performed to a sequence of the data detected at each step-like stop point of the movable mirror 6 to obtain a spectrum of the sample 3. Since most of absorption of the infrared rays by elements except the sample 3 is isotropic to the polarization, a background component except the sample can be eliminated.
