    摘要: A battery capable of obtaining the high energy density and obtaining the superior cycle characteristics is provided. In an anode, the thickness of a single face of an anode active material layer containing a carbon material as an anode active material is from 75 μm to 120 μm. An electrolytic solution contains difluoroethylene carbonate as a solvent. Thereby, the energy density of the anode is improved, and the diffusion and the acceptance of lithium ions in the anode are improved.

    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.
