<P>PROBLEM TO BE SOLVED: To raise capacity and charge of a negative electrode material, and to improve low-temperature load characteristic, in regard to a nonaqueous electrolyte battery. <P>SOLUTION: This nonaqueous electrolyte battery is provided with a positive electrode 2, a negative electrode 3 and nonaqueous electrolyte. In the negative electrode, graphite, of which Gs value to be obtained by using an expression (1) on the basis a surface increased Raman scattering spectrum measured by using argon laser beam is restricted to 20 or less, is used as a negative electrode active material. In the expression (1), Gs=H<SB>sg</SB>/H<SB>sd</SB>. In the expression, H<SB>sg</SB>means height of a signal which has a peak in a range at 1580 cm<SP>-1</SP>-1620 cm<SP>-1</SP>, and H<SB>sd</SB>means height of a signal which has a peak in a range at 1350 cm<SP>-1</SP>-1400 cm<SP>-1</SP>. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
