に夫々接続片を取付る必要がある。 Because this type of battery has the advantages of high voltage and high energy density, silver batteries are replacing mercury batteries as power sources for calculators and electronic watches, and more recently, they have also been used as power sources for memory in electronic circuits. In particular, it is being used as a memory backup power source during power outages, but in this case, the battery is built into a printed circuit board like electronic components, so it is connected to the positive and negative terminals of the battery, which also serve as the positive and negative terminals, respectively. You need to install the pieces.

When welding by spot welding, the negative electrode with a low melting point (lithium 180℃, sodium 98℃) is damaged by the heat during spot welding.
There is an inconvenience that the separator that separates the positive and negative electrodes also melts and removes internal short circuits.
