作業においても高精度が要求されるものであった。For example, in a high-output flat lithium battery that uses a pair of positive and negative electrode plates, both the positive and negative electrode plates are formed into a glasses shape that is joined by a current collector, and these plates are separated by a separator. The structure was such that each electrode plate was bent in a predetermined direction and stacked on top of the other.
There was a concern that internal short circuits could occur due to distortion of the connector, and high precision was also required in the assembly work.

１の内底面に圧接して電気接続されている。Further, a second negative electrode plate 5 is disposed on the second separator 6b.
b, the second negative electrode current collector 4b, the third separator 6c and the second positive electrode plate 8b are stacked, and then the positive electrode current collector piece 7' which can be led out from the first positive electrode plate 8a is placed on the second positive electrode plate. This positive electrode current collector piece γ is electrically connected to the inner bottom surface of the sealing lid 1 which also serves as a positive electrode terminal by being pressed against the inner bottom surface of the sealing lid 1.

Therefore, the conductive rod 10 can prevent the electrode plate group from shifting, and the conductive rod 10 can also prevent the electrode plate group from shifting.
, 5b can be electrically connected.
上述した如く、本考案は極板ズレを因とする内部短絡を

続状態が保持されることになる。Furthermore, since the pair of negative electrode plates that are electrically connected by the conductive rod are made of lithium plates, which are soft metals, the ends of the conductive rods bite into the lithium plates, and a good electrical connection is maintained between the conductive rods and the negative electrode plates. That will happen.
