Application 09/770,725
1 that a strip-like laminate body comprising a positive electrode
2 4, a separator 5, and a negative electrode 6 stacked in this order
3 is spirally wound with the separator being disposed at the
4 outermost side of the electrode assembly 3. (Takami, 4:7-15;
5 Figure 1.)
6 5. Takami teaches that the positive electrode may be made from
7 “various kinds of oxides,” thus indicating to one skilled in the
8 relevant art that the oxides for use as the positive electrode
9 material are not particularly limited. (Takami, 4:39-46.)
10 6. Nevertheless, Takami states that lithium cobalt oxide, lithium
11 nickel oxide, and lithium manganese oxide are preferred.
12 (Takami, 4:46-49.)
13 7. Takami further teaches that the carbonaceous material of the
14 negative electrode should be a multi-phase structure having a
15 region of graphite structure and a region of amorphous carbon
16 structure. (Takami, 5:2-7.)
17 8. As to the non-aqueous electrolyte, Takami discloses that a
18 lithium salt such as lithium hexafluorophosphate (LiPF6),
19 among other possibilities, may be incorporated. (Takami,
20 10:41-48.)
21 9. That Takami describes a “positive electrode active substance
22 comprising lithium manganese oxide,” a “negative electrode
23 active substance comprising at least one material selected from
24 the group consisting of amorphous carbonaceous material and
25 graphitized carbonaceous material,” “a non-aqueous electrolytic
26 solution containing a lithium compound as an electrolyte,” and
