    Abstract: A non-aqueous electrolyte battery includes a cathode, an anode and a non-aqueous electrolyte. The anode uses as an anode active material graphite whose Gs value obtained by a formula (1) from a surface-enhanced Raman spectrum measured by using an argon laser beam is 20 or smaller. Gs = Hsg/Hsd ... (1) (Here, Hsg represents the height of a signal having a peak within a range of 1580 cm-1 to 1620 cm-1 and Hsd represents the height of a signal having a peak within a range of 1350 cm-1 to 1400 cm-1.) Thus, the high capacity, the high filling characteristics and the low temperature load characteristics of an anode material are improved.

    Abstract: PROBLEM TO BE SOLVED: To provide a positive electrode material, of which characteristics in charge and discharge cycle, quality preservation characteristics and discharge load characteristics are improved, and to provide a secondary battery using it. SOLUTION: A wound electrode 20, made by winding positive 21 and negative electrode bands 22 via separators 23 is settled in a battery can 11. The separator is impregnated with an electrolytic solution. The positive electrode is composed of a positive electrode material, which has a center part formed of a lithium composite oxide, such as LiMn2O4 and a covering part on the surface of the center part. The covering part is formed of an ITO or an electroconductive oxide such as SnO2. Quantity of the covering part is more than 0.001 mol and less than 0.1 mol for the center part of 1 mol. This restrains dissolution of the positive electrode material into the electrolytic solution, with conserved conductivity and prevents precipitation and accumulation of reaction products on the positive electrode due to repeated charging and discharging operation.

    Abstract: PROBLEM TO BE SOLVED: To provide a positive electrode material which improves charge and discharge cycle characteristics, preservation characteristics, and discharge load characteristics, and a secondary battery using the same. SOLUTION: The secondary battery includes a wound electrode body 20 in which a belt shape positive electrode 21 and a negative electrode 22 are wound around through a separator23 inside a battery can 11. An electrolyte solution is impregnated in the separator 23. The positive electrode includes a positive electrode material in which a covering part is provided on the surface of the central portion consisting of a lithium compound oxide such as LiMn 2 O 4 . The covering part is constituted of a conductive oxide such as ITO or SnO 2 , and the quantity of the covering part is 0.001 mol or more and 0.1 mol or less against the central portion 1 mol. Thereby, it is controlled that the positive electrode material is eluted into the electrolyte solution while securing conductivity and it is prevented that a reaction product is precipitated and accumulated on the surface of the positive electrode even if charge and discharge are repeated.
