。[Detailed Description of the Invention] [Field of Industrial Application] This invention uses a valve metal as an anode, and forms a dielectric oxide film layer on the surface of the valve metal to oppose lithium of the cathode through an electrolyte. - Concerning lithium capacitors.

陽極酸化により誘電体となる酸化アルミニウム層を形成
し、液体電解質を介して陰極側の皮膜形成されていない
アルミニウム電極と対抗した構造を有している。Metals such as aluminum, tantalum, titanium, and niobium that have an insulating oxide film formed on their surface through oxidation treatment, that is, valve metals (also called valve metals or barrier metals), have an oxide film that is insulating. Since it is also extremely thin, it is used as a dielectric material in capacitors. Electrolytic capacitors utilize this principle. For example, aluminum is used as an anode, an aluminum oxide layer is formed as a dielectric on the surface of the anode, and a film is formed on the cathode side via a liquid electrolyte. It has a structure that is opposed to aluminum electrodes.
この電解コンデンサは、酸化アルミニウム皮膜の誘電率

ないし30人程度と極めて薄いため小型で高静電容量の
コンデンサが得られる。This electrolytic capacitor has an aluminum oxide film with a high dielectric constant of around 30, and a film thickness of 10 per IV.
Since it is extremely thin, measuring about 30 to 30 people, a small capacitor with high capacitance can be obtained.

はるかに低い値しか得られなくなる。By the way, in the case of this electrolytic capacitor, when the operating voltage is low, such as several volts or less, due to the natural oxide film formed on the surface of the aluminum used for the cathode,
A capacitor has a dielectric layer connected in series with an anode and a cathode, and the combined capacitance becomes capacitance, so especially when used in a low voltage region, the capacitance value is much higher than the desired capacitance value. Only low values will be obtained.

とができる。As an improvement on this drawback, for example, JP-A-61-1
There is a capacitor using lithium as a cathode, as disclosed in Japanese Patent No. 84812. Since this capacitor uses lithium or its alloy for the cathode, an insulating layer of natural oxide film is not formed on the cathode surface, so no composite capacitance is formed.
Decrease in capacitance can be prevented. In addition, since lithium itself has a negative potential, it absorbs a portion of the withstand voltage of the dielectric oxide film and can increase the apparent working voltage.
Capacitance can be increased by forming a thin dielectric oxide film.

られしたもので、アルミニウム等の弁金属からなる陽極
体1が中央部に配置されている。FIG. 2 shows a modified structure of a conventional valve metal-lithium capacitor, in which an anode body 1 made of a valve metal such as aluminum is placed in the center.

ゆる焼結型などの構成であってもよい。The anode body 1 has a configuration such as a coiled valve metal in the form of a foil, or a so-called sintered type in which powdered valve metal is pressure-molded together with a binder and then fired to scatter the binder to create a porous structure. It may be.

状の陰極3が配置されている。A foil-shaped cathode 3 is arranged on the outer peripheral surface of the anode body 1 so as to surround the outer periphery of the anode body 1 with an ion-permeable porous separator 2 in between.

浸漬されている。The capacitor element part 4 composed of the anode body 1, the separator 2, and the cathode 3 contains a non-aqueous electrolyte in which inorganic, organic, or organometallic anions including lithium ions are present in a solvent such as propylene carbonate or butyrolactone. is immersed.

The opening of the exterior case 5 is sealed by a sealing member 6.

くする原因となっていた。In such conventional valve metal-lithium capacitors, the cathode 3 was placed on the outer periphery of the anode body 1 with the separator 2 in between, so the external size of the cathode 3 was large, which hindered miniaturization. . Furthermore, the element configuration is complicated and it takes time to assemble the capacitor element section 4. Furthermore, since the cathode 3 is made of lithium itself or a metal containing lithium, which is extremely sensitive to moisture, the assembly work must be performed in a dry box that prevents moisture from entering, which causes poor workability. It had become.

。Although not shown, the cathode 3 may be arranged at the bottom of the circular end face of the cylindrical anode body 1. Further, the cathode 3 may be placed on both the periphery and the bottom surface, but in this case, the assembly of the capacitor element becomes even more complicated, and the external size becomes even larger.

It is said that
以下実施例に基づきこの発明の詳細な説明する。 The present invention will be described in detail below based on Examples.

7が接続されている。In the figure, an anode body 10 is formed into a cylindrical shape by winding aluminum foil. The foil-shaped aluminum of this anode body 10 has been electrolytically etched to make its surface corrugated, and furthermore, a dielectric oxide film layer is formed on the surface by anodizing. In this example, high-purity aluminum foil with a thickness of 80 μm was used.
After the surface was corrugated by electrolytic etching, a dielectric layer was formed at a voltage of 4 V for anodic oxidation, which was then cut into strips and wound. An aluminum rod with a flattened tip as an anode tab 11 is placed approximately in the center of this aluminum foil so that the flattened portion abuts the electric scraping foil, and electrical connection is made by stitching. An anode lead wire 1 is attached to the outer tip of this anode tab 11.
7 is connected.

After drying at 250°C for 10 minutes, it was impregnated with an electrolytic solution in which IM's lithium borofluoride (LiBF4) was dissolved in propylene carbonate solvent, and the diameter was 12.5ml and the height was 15mm.
It was housed in 11 bottomed cylindrical aluminum cases 13.

3 was used as a cathode, and a lithium layer 14 was formed on the inner surface by doping. Further, a cathode lead wire 15 is connected to the center of the outer bottom surface of the aluminum case 13 by welding.

このようにして完成した弁金属−リチウムコンデンサを

00μFのコンデンサが得られた。As a result of aging the valve metal-lithium capacitor thus completed at a voltage of 6μ for 4 hours, the capacitance was 77.
A capacitor of 00 μF was obtained.

きる。With the above configuration, the anode body 1 and the lithium layer 14 on the inner surface of the aluminum case 13 serving as the cathode face each other with the separator paper 12 in between, thereby forming a capacitor. In addition, for electrical connection with the outside, the anode side is connected to the anode body 1.
0, the anode lead wire 17 is connected to the tip of the anode tab 11, and the cathode side is connected to the aluminum case 1.
This can be done by using the cathode lead wire 15 connected to 3.
なお、この実施例では陽極体としてアルミニウムを用い
たが、タンタル、ニオブ、ジルコニウム、チタン等の他
の弁金属を用いることもできる。Although aluminum was used as the anode body in this embodiment, other valve metals such as tantalum, niobium, zirconium, titanium, etc. can also be used.

孔質体であっても勿論差支えない。In addition, although the anode body structure is one in which a foil-like metal is wound in the example, it is of course possible to use a porous body made by sintering valve metal powder.

れるものではなく、対峙する外装ケースの内面に沿うも
のであれば角柱状、直方体等でもよい。Further, the shape of the anode body is not limited to the cylindrical shape of this embodiment, but may be a prismatic shape, a rectangular parallelepiped, etc. as long as it follows the inner surface of the facing exterior case.
さらに、実施例では外装ケース内面のリチウム層形成に

して用いてもこの発明の目的は達することができる。Furthermore, in the example, a lithium layer was formed on the inner surface of the outer case by doping treatment, but the lithium layer could also be made of a clad material of aluminum and lithium, for example, with lithium coated on the inner surface. The object of the present invention can also be achieved by forming the case in this manner, or by using an alloy of lithium and aluminum or other metals as the outer case.

に別にリチウム陰極を陽極体に対峙して取り付ける必要
がなく、コンデンサ製造工程を大幅に簡略化できる。As described above, according to the present invention, a valve metal is used as an anode body, and a lithium layer is formed on at least the inner surface of the outer case that houses the anode body, so unlike the conventional case, a lithium cathode is formed separately. There is no need to install it facing the anode body, which greatly simplifies the capacitor manufacturing process.
また、陰極が外装ケースで代用できるので、コンデンサ
の外形形状を小さくすることができる。Furthermore, since the cathode can be replaced by an external case, the external shape of the capacitor can be made smaller.

It is something that
