It has a characteristic of having a high electromotive force of 3 V and 4 V, and its excellent performance has been attracting attention.

As metal materials that can withstand such a high voltage, titanium, special SUS, precious metals such as gold and platinum, and aluminum have been very limited.
In particular, in the case of a hermetically sealed battery that requires high hermeticity, the positive electrode pin material is further limited because it needs to have a value close to the thermal expansion coefficient of fused glass, and only titanium or a special SUS material is used. I could not do it. Titanium and special SUS materials are both expensive,
There were major difficulties in workability and weldability.

It is an object of the present invention to provide a new positive electrode terminal that does not have the above-mentioned problems by devising an insulation method that does not rely on glass.

るようにしたものである。In order to solve the above-mentioned problems, the present invention uses a positive electrode pin made of Al or an Al alloy, and the positive electrode pin is connected to a battery can via a gasket made of resin in which the positive electrode pin is divided into upper and lower parts. By adopting a positive electrode terminal structure for a battery, which is characterized by being crimped on the battery lid,
It is possible to use Al or Al alloy having excellent withstand voltage as a positive electrode pin material, and to provide an inexpensive and useful material as a positive electrode terminal of a battery having an electromotive force of 3 V or more.

場合、ＡｌもしくはＡｌ合金が最適の材料である。As described above, the metal material that can withstand high electromotive force is
Al or Al alloy is the most suitable material in view of price and workability because it is extremely limited.

気的に絶縁されていなければならない。In order to use Al or Al alloy as the positive electrode pin, it must be electrically insulated from the battery can or the battery lid that serves as the negative electrode terminal.

Although the above-mentioned hermetic sealing method is disclosed in Japanese Patent Publication No. JP-A-2003-242, the difference between the thermal expansion coefficient of Al or Al alloy and that of the fused glass is too large. The product cannot be obtained due to cracking.

Alternatively, it is possible to obtain a positive electrode terminal excellent in electrical insulation and airtightness by caulking a pin made of an Al alloy into a battery can or a battery lid through a resin gasket that is divided into upper and lower parts. I found it.
