池にリード板を溶接する場合、リチウムの融点が179℃
なのでリチウムが溶融してセパレータを貫通し、内部短
絡の原因となること及び製造コストが高くなる等の欠点
があった。Conventionally, since a thin battery of this type does not have a terminal portion, a method has been proposed in which a lead plate is spot-welded to the battery itself and connected to a device. However, when welding a lead plate to a lithium battery, the melting point of lithium is 179 ° C.
Therefore, there are disadvantages that lithium melts and penetrates through the separator to cause an internal short circuit and increase the manufacturing cost.
