`

`Remarks
`
`The Applicants have amended Claim 1 to include the subject matter ot‘Claim 3.
`
`Claim 3 has been cancelled in View ol‘the inclusion ofthat subject matter into Claim 1.
`
`Claim 4 has also been amended to depend from Claim 1
`
`in View of the cancellation of
`
`Claim 3.
`
`Finally, Claim 7' has similarly been amended in View of the cancellation of Claim 3.
`
`Entry of the above amendments and cancellation into the official file and consideration
`
`on the merits is respectfully requested.
`
`The Applicants enclose a new Fig. 4 and respectfully request that it be entered into the
`
`official file.
`
`The drawings stand objected to with respect to the claimed insulator which prevents
`
`direct mechanical and electrical contacts between the end faces of the winding and the flat
`
`bottom of top areas must be shown. The Applicants note that original Claim 4 shows such an
`
`insulator with respect to reference numbers 41 l and 412. However, the originally submitted Fig.
`
`4 shows a button cell that is closed in a classical manner with an edge of the cell cup 401 being
`
`beaded inward over an edge of the cell top 402. New Fig. 4 has been modified such that the
`
`button cell 400 is closed without being beaded over in accordance with Claim 1 and, also, in
`
`accordance with the claimed feature wherein the insulator prevents direct and electrical contact
`
`between the end faces of the winding in the flat bottom and top areas. Withdrawal of the
`
`objections to the drawings is respectfully requested.
`
`Claims 1. 2, 6. 10 and 11 stand rejected under 35 USC {$102 as being anticipated by
`
`Nakayama. The Applicants respectfully submit that the rejection is moot in View of the addition
`
`EAS’TWSS‘IGSOH

`
`JLab/Cambridge, Exh. 1002, p. 333
`
`JLab/Cambridge, Exh. 1002, p. 333
`
`

`

`of the subject matter of Claim 3 into Claim 3. Withdrawal of the rejection is respectfltlly
`
`requested.
`
`Claims 3-5, 9. 12 and 13 stand rejected under 35 USC §103 over the combinatiori of
`
`Suzuki with Nakayama. The Applicants note that the rejection is technically moot with respect
`
`to cancelled Claim 3. Nonetheless, the Applicants will address the substance 01‘ that rejection as
`
`it could theoretically apply to Claims l and ll.
`
`The rejection frankly acknowledges that Nakayama does not disclose a spiral winding.
`
`Hence, the rejection turns to Suzuki for such disclosure. However, the Applicants respectfully
`
`submit that importing the teachings of Suzuki
`
`into Nakayama would still result in a different
`
`button cell and a different method of producing a button cell as recited in Claims 1 and 11.
`
`respectively.
`
`Suzuki indeed discloses a spiral winding (Fig. 2). However, the end faces of the winding
`
`in Fig. 2 of Suzuki do not face in the direction of the flat bottom area and the flat top area. This
`
`difference is important. The Applicants explain in para. [0020] of their specification that a right—
`
`angled alignment of electrode layers (to the flat bottom and top areas)
`
`is unexpectedly
`
`advantageous. Lithium electrodes have a volume expansion and shrink during charging and
`
`discharging. It'a lithium electrode is in the form ot'a flat layer, in particular in the form ofa flat
`
`layer being spirally winded,
`
`the expansion/shrink .is directional. Mechanical forces resulting
`
`from the expansion/shrink do act in this case in a radial direction much stronger than in an axial
`
`direction.
`
`This allows the use of a housing of a housing cup and a housing top which is closed
`
`without being headed over. All mechanical forces resulting from the charging and discharging
`
`processes can be absorbed by the (radial) casing area and not by the flat bottom and top areas.

`{Detailed Description of the invention]
`{Field of the Invention]
`[00013
`The present invention relates to the sized cell (for example, a button type battery, a coin type cell)
`provided with the winding electrode group.
`{Background of the Invention}
`{0002]
`The spread of a portable electron and communication equipment, such as a small video camera, a
`cellular phone, PDA, and a notebook computer. was remarkable, rechargeable batteries, such as a
`rechargeable lithium~ion battery and a nickel hydrogen storage battery, were put in practical use as
`these power supplies, and development towards small weight saving and high capacity—ization has been
`performed briskly.
`{0003]
`in addition to the flow of the further miniaturization of a portable equipment, a rechargeable battery is
`required as a power supply of the apparatus made indispensable [a miniaturization called a wrist
`watch 3, Small rechargeable batteries, such as a button form and a coin form, have been put in
`practical use by uses, such as a power supply for backup of SRAM and RTC to which discharge is
`performed with the light load whose discharge current is a number _ a tens of mlcroA grade, and a
`main power supply of a changing~battery unnecessary wrist watch.
`[0004]
`As for the structure of small rechargeable batteries, such as these button type and a coin form, what
`
`is shown in Fig/l0 is common, That is, that by which the positive electrode case 21 which serves as a
`positive pole terminal was oaulked via the insulating gasket 23 as a well—closed container in the metal
`negative electrode cases 22 which serve as a negative pole terminal is used. Inside this well~closed
`container, one the positive electrode 24 and the anode 25 of the shape of a tablet whose diameter is
`smaller than the opening diameter of the insulating gasket 23 are stored at a time, respectively,
`Between the positive electrode 24 and the anode 25. the separator 26 which made the electrolysis
`solution impregnate interposes.
`{00053
`Since small rechargeable batteries. such as such a button Form and a coin form, are simple for
`structure, they are excellent in mass production nature, and have the characteristics that a
`miniaturization is possible.
`{00003
`However, small rechargeable batteries, such as a button Form of the structure shown above and a coin
`form, have the insufficient characteristic at the time of discharging in the high current demanded as a
`main power supply of a portable device, and are not suitable as a main power supply of a portable
`device,
`{0007}
`A miniaturization is indispensable about a rechargeable lithium~ion battery, a nickel hydrogen storage
`battery, etc. which have been used by the miniaturization of personal digital assistants. such as a small
`video camera, a cellular phone, PDA, and a notebook computer, as a main power supply on the other
`hand (for example, a Patent document 3, 2}, The manufacturing method of a rechargeable lithium-ion
`battery or a nickel hydrogen storage battery is described simply. First, the charge collector consisting
`of a metallic foil or a metal net is applied or filled up with an active material layer, and an electrode is
`formed, An electrode group is produced by winding or laminating these electrodes after welding the tab
`terminal for current collection to the formed electrode. Bending was intricately performed to the tab
`terminal for current collection furthermore taken out from the electrode group, it welded to a safety
`element. an electrode pin, an electrode can, etc, and the cell was manufactured This appearance
`takes a complicated manufacturing process to manufacture of these rechargeable batteries, and its
`work is complicated, It is necessary to provide space and parts in a cell for short prevention of a tab
`terminal, or to incorporate many parts, such as a safety element, in a cell, Therefore, in these
`rechargeable batteries, the miniaturization was dramatically difficult and had reached the limit
`substantially in the actual condition,
