- Alkali metals such as lithium, sodium, and calcium or their alloys are used as the negative electrode active substance, and thionyl chloride, sulfuryl chloride, and phosphoric chloride, which are liquids at room temperature, are used as the positive electrode active substance.
- the so-called liquid active substance battery using oxyhalides such as metal has high energy density, excellent storage characteristics, and a wide operating temperature range, and is widely used as a power source for memory backup of industrial equipment. ing.
- a negative electrode active material made of aluminum metal or an alloy thereof is generally press-bonded to an inner peripheral surface of a can body also serving as a negative electrode terminal, and a positive electrode body mainly composed of porous carbon is provided in the can body. It is installed via a separator.

- the positive electrode body is made of porous carbon and a positive electrode current collector such as a metal mesh or a metal rod.
- the negative electrode active substance and the positive electrode active substance In such a liquid active substance battery, the negative electrode active substance and the positive electrode active substance However, a protective film is formed on the surface of the negative electrode active material, which is a reaction product of the positive electrode active material and the electrolyte dissolved therein (alkali metal salt such as lithium chloride). It suppresses the direct reaction between the electrolyte and the liquid cathode active material, preventing the battery from self-discharging and also avoiding heat generation, thereby contributing to battery safety.
- alkali metal salt such as lithium chloride
- these batteries are often used by bonding external terminals and connectors to the battery due to their application, and welding the external terminals and lead foil to the bottom and top of the battery by spot welding, etc. Often used.

What is described in this document is that This countermeasures the situation in which, when dropped into a solder bath, high-temperature heat is instantaneously applied in large quantities and explodes before the explosion-proof function operates, but as a secondary effect, the external It has been shown that the danger of battery rupture during terminal welding can be dealt with, and as a countermeasure, it has been shown that a resin ring such as polytetrafluoroethylene is inserted into the bottom of the battery can. I have.
- the resin cyclic body is substantially made of a fluororesin such as polytetrafluoroethylene because of its thermal stability and resistance to oxyhalides, and this fluororesin and lithium as the negative electrode active substance are used. It is not preferable because it reacts to form lithium fluoride.
- the resin ring may come off or tilt before the negative electrode active material is pressed onto the battery can, resulting in mass production of batteries. However, it could not be said that this could be a sufficient measure.
- the present invention has been made in view of the above circumstances, and in a liquid active material battery in which external terminals are welded after the battery is assembled, a position shift occurs in a negative electrode active material that is crimped on the inner surface of the battery can, and the bottom surface of the battery can is damaged.

It is desirable that the space between the metal plate and the battery can be at least 0.2 mm, and it is practically between 0.3 mm and 0.6 mm. If the space is less than 0.2 mm, the welding heat may be transferred to the protruding negative electrode active material if the battery can is deformed by the pressure received from the welding rod during external terminal welding. Also, if the space is made thicker, the internal volume of the battery is reduced correspondingly, and the discharge capacity of the battery is reduced.
