Appeal No. 2004-1101
Application No. 09/262,325
wherein said coiled electrode comprises an
elongated positive electrode, and elongated negative
electrode, and a separator, said positive electrode
and negative electrode separated by the separator and
wound so that the positive electrode forms an
outermost electrode of the coil;
wherein said positive electrode comprises a
positive-electrode mix layer and a positive-electrode
collector made of a metallic foil having a first
surface, a second surface, an outermost end, and an
innermost end;
wherein said positive-electrode mix layer is not
formed on either the first or second surface of the
positive electrode collector at the outermost end of
the positive electrode collector;
wherein said positive-electrode mix layer is
formed on either but not both of the first or second
surfaces of the positive electrode collector at a
position adjacent to the outermost end of the positive
electrode collector;
wherein said positive-electrode mix layer is
formed on both the first and second surface of the
positive electrode collector on at least a portion of
the positive electrode collector;
wherein said negative electrode comprises a
negative-electrode mix layer containing a negative-
electrode material which permits lithium ions to be
doped/dedoped and a negative-electrode collector made
of a metallic foil having a first surface, a second
surface, an outermost end, and an innermost end;
wherein said negative-electrode mix layer is not
formed on either the first or second surface of the
negative electrode collector at the outermost end of
the negative electrode collector;
wherein said negative-electrode mix layer
material is formed on both the first and second
surface of the negative electrode collector on at
