As disclosed in Publication No. 4 or Japanese Patent Publication No. 395゜7 of 1982, lithium is used as the negative electrode active material and manganese dioxide or fluorocarbon is used as the positive electrode active material.
It is known that a polyolefin nonwoven fabric such as polyethylene in polypropylene is used as a separator.
Since it has the advantages of high energy density and low self-discharge, it is suitable for applications such as memory backup power supplies (Field C that requires long-term reliability of -10 years or more).

の結果内部短絡を引起すこと６二なる。By the way, when used as a memory backup power source, for example, batteries can be used in the same way as electronic components - printed circuit boards.
Since it is an integrated method, it is necessary to attach connection pieces to the positive and negative terminals of the battery, respectively. And when welding when installing this connection piece, C: Local C: is a negative electrode (lithium, melting point 18
0'C) and separator (Volip μpyrene, melting point 160
Since the temperature is higher than the melting point of polyethylene (polyethylene, melting point: 110-140°C), the separator melts and breaks, resulting in internal short circuits.

For example, since we used a synthetic resin separator made of high melting point polyimide resin (melting point 700°C) as the main component, the heat I during welding when attaching positive and negative electrode cans ≦ 2 connection pieces is higher than that of the separator. Melting is suppressed.

(l) is a positive electrode can made of a stainless steel plate having a thickness of CL2jlll, and a positive electrode (2) having a thickness of 0.65111 mm and containing manganese dioxide as an active material is pressed onto the inner bottom surface I:. (3) is a negative electrode can made of a stainless steel plate with a thickness of 0.2111I, and the inner bottom surface C2 has a thickness of Q, 5
A negative electrode (4) made of a yzyx lithium rolled plate is crimped and an insulating backing (5) is attached to the periphery of the negative electrode (5).

It is placed on the piece (7) and welded by applying electricity as shown by the arrow, but the welding heat I:
Therefore, even if a part of the lithium negative electrode (4) melts, the separator (6) does not melt and separate, so no internal short circuit occurs.
