Appeal 2007-1524
Application 09/770,725
1 20. Kurose discloses a non-aqueous electrolyte battery including a
2 nickel-containing lithium composite oxide as an electrode
3 active material. (Kurose, 2:35-40.)
4 21. Kurose’s nickel-containing lithium composite oxide has the
5 formula LixNiyMzO2 (where x satisfies 0.8<x<1.5, y+z satisfies
6 0.8<y+z<1.2, z satisfies 0≤z<0.35, and M is at least one
7 element selected from Co, Mg, Ca, Sr, Al, Mn, and Fe).
8 (Kurose, 2:35-43.)
9 22. In the working examples, Kurose teaches the use of the nickel-
10 containing lithium composite oxide as a positive electrode
11 material, metallic lithium as a negative electrode, and a non-
12 aqueous electrolytic solution containing LiPF6. (Kurose, 8:42-
13 67.)
14 23. Kurose teaches (2:14-18):
15 Use of an active material in a state with a lot of
16 absorbed moisture in battery causes problems such
17 as a decrease in a charge/discharge capacity of the
18 battery, increase in internal resistance, and
19 deterioration of the preservation property.

21 24. Applicants rely on the 37 CFR § 1.132 Declaration of Toshihiro
22 Yoshida, one of the named inventors, to demonstrate that
23 “nickel-containing lithium composite oxides do not behave in a
24 manner anywhere near equivalent to LiMn2O4.” (Reply Br. 1 at
25 4.; Declaration under 37 CFR § 1.132 filed on April 8, 2005.)
26 25. The Yoshida Declaration states the purpose of the experiments
27 discussed therein as “to show the effect of HF in electrolyte
28 solutions upon dissolution of transition-metal contained in
