Description
【発明の詳細な説明】 産業上の利用分野 本発明は、有機電解質電池の改良に関するものである。[Detailed description of the invention] Industrial applications The present invention relates to improvements in organic electrolyte batteries.
従来の技術
リチウムを活物質とする有機電解質電池は、高エネルギ
ー密度を有するところから、電子ウォノ２Ａ−。Conventional technology Organic electrolyte batteries using lithium as an active material have a high energy density, so they are popular among electronics users.

のだめに、電子ウォッチなどのパルス放電を行なうと、
閉路電圧の低下が大きくなシ、電池容量を最後まで有効
に使用できなくなる。It is attracting attention as a power source for various small electronic devices including chips. However, since metallic lithium is very active, internal resistance increases due to the formation of a lithium compound film on the lithium surface, and furthermore, as discharge progresses, internal resistance increases due to a decrease in the lithium surface area. . To no avail, if you use a pulse discharge such as an electronic watch,
If the drop in closed circuit voltage is large, the battery capacity cannot be used effectively to the end.
このような欠点を解消するだめに、リチウム表面にアル

極の微細化状態やシワ状態によシ負極表面積を増大させ
、内部抵抗を低下させるという提案がなされている。In order to eliminate these drawbacks, aluminum foil is attached to the lithium surface, which increases the negative electrode surface area and lowers the internal resistance by reducing the fineness and wrinkles of the negative electrode that occur due to the formation of an alloy layer. Suggestions have been made.

、アルミニウム合金化されずに残シ、リチウムの反応を
阻害して放電容量を低下させる等の問題があった。Problems to be Solved by the Invention However, when ordinary aluminum foil is used, the electrolyte is reduced by the volume of the aluminum foil, which lowers the reaction efficiency of the battery, leading to a decrease in capacity. Deterioration of discharge characteristics occurs. In addition, with ordinary aluminum foil, the contact area with 37,-7 lithium is small, so alloying does not proceed uniformly, the alloy layer on the surface facing the positive electrode has coarse particles, and the increase in the negative electrode surface area is small. Satisfactory pulse characteristics cannot be obtained either. Furthermore, when the thickness of the aluminum foil becomes thicker, there is a problem that the aluminum foil is not alloyed with aluminum, and the reaction of residual lithium is inhibited, resulting in a decrease in discharge capacity.
本発明は上記のような問題点を解消し、電解液の減少を

The battery is constructed by placing it on the lithium reaction surface of the negative electrode.

定した放電特性を得ることが可能となる。Function: By constructing a battery using this aluminum foil, the electrolyte permeates into the tunnel pit inside the aluminum foil, preventing the electrolyte from decreasing and reducing reaction efficiency. In addition, since the surface area of the aluminum foil is increased by the tunnel pit, the alloying process between aluminum and lithium is quick and uniform, and a fine particle-like alloy layer can be obtained. This eliminates the occurrence of unalloyed aluminum parts, resulting in low internal resistance and excellent pulse discharge characteristics, making it possible to obtain stable discharge characteristics.

The positive electrode 6 is an aluminum foil according to the present invention, which is press-bonded together with the positive electrode ring 5.
An aluminum foil that has been annealed in advance at 300°C is electrochemically etched to have a through tunnel pin. Annealing was performed in a nitrogen atmosphere to prevent oxidation of the aluminum foil. Normally cold-rolled hard foils have complex dislocation cells, but annealing at 250"C or higher causes recrystallized grains to grow, resulting in less surface deformation and perpendicular to the foil surface during etching. A foil with a large number of focuses can be obtained.The thickness of the foil used was 40 μm.7 is a polypropylene separator 8 is a polypropylene gasket.Electrolyte Niha, propylene carbonate, and 1-2
