    摘要： A powdered graphite and a nonaqueous electrolyte secondary battery are provided. A nonaqueous electrolyte secondary battery is provided which has a highly efficient charge and discharge performance and superior cycle properties. Spheroidizing treatment is appropriately performed for natural graphite having a high capacity by grinding and/or applying impact to form a negative electrode active material, and a negative electrode active layer formed therefrom is provided on a metal electrode foil. Subsequently, the metal electrode foil is applied with a magnetic field so that the spheroidized natural graphite is oriented, followed by drying and compression molding, thereby forming a negative electrode. By the use of this negative electrode, a nonaqueous electrolyte secondary battery can be formed having superior battery properties such as the cycle properties and peeling strength.

    摘要： A secondary battery which employs a non-aqueous solvent for the electrolyte and which includes a positive electrode formed of a compound oxide of lithium and a negative electrode of a carbonaceous material is disclosed. The non-aqueous electrolyte, comprised of an electrolyte dissolved in the non-aqueous solvent, is employed in such secondary battery. According to the present invention, a mixed solvent composed of propylene carbonate and methyl ethyl carbonate is employed. The volume ratio of propylene carbonate to methyl ethyl carbonate is 6:4 to 3:7 and preferably 4.5:5.5 to 3:7. As the electrolyte, LiPF.sub.6 is dissolved at a concentration of 0.6 to 1.8 mol/lit. The battery is not increased in its internal pressure even when employed under a high temperature environment, while its electrolyte is not solidified when the battery is employed under a low temperature environment, such that a high energy density, a long service life and high operating reliability may be achieved over a broad range of the working temperature.
