In addition to the process of forming a bag-like separator by forming a non-woven sheet into a bag-like shape, and the process of making a cylindrical cylindrical negative electrode, both the bag-like separator and the lithium negative electrode are placed inside a positive electrode can. There is a problem that a two-step insertion process is required to accommodate the separator, which complicates the manufacturing process.Also, when inserting the cylindrical negative electrode into the bag-shaped separator, the work is not easy. In order to facilitate insertion, it is necessary to make the outer diameter of lithium somewhat smaller than the inner diameter of the separator.As a result, the adhesion between the lithium negative electrode and the separator deteriorates, and the distance between the electrodes increases during battery assembly. This causes problems such as the internal resistance of the battery increases and the discharge characteristics become poor.

著しく煩雑化するといった問題がある。On the other hand, in the case of wrapping a non-woven fabric sheet around a cylindrical lithium negative electrode, not only the forming process of the cylindrical lithium negative electrode and the wrapping of the non-woven fabric sheet must be performed separately, but also the separator wrapped around the lithium negative electrode must be separated. It is necessary to treat the terminals at the bottom, especially when the internal diameter of the lithium negative electrode is small in small batteries, the workability of the insertion part into the hollow part of the mixture during folding and after folding is extremely poor, and the manufacturing process becomes extremely complicated. There's a problem.

および底面側にはみ出たセパレータ端部をリチウ 。<Means for Solving the Problems> The button-type lithium battery manufacturing method of the present invention was developed in view of the above-mentioned problems. In this manufacturing method, a larger sheet-shaped separator is superimposed on one side of a plate-shaped lithium negative electrode, and the ends of the separator protruding from both sides and the bottom side of the lithium negative electrode are removed.

負極集電体により覆われているだけでもよい。Examples of the negative electrode current collector include sheet metal nets (extended stainless steel plates, etc.) and metal plates (stainless steel plates with cut and raised pieces, panned metal, etc.). For example, when a sheet-shaped metal net is used and crimped onto the other surface of the lithium negative electrode, the separator end is sandwiched between the peripheral edge of the metal net and the lithium negative electrode and aligned to the other surface of the lithium negative electrode. Ru. In addition, if a protrusion is formed at the end of the negative electrode current collector, and the protrusion penetrates the separator end and bites into the lithium negative electrode when crimped with the lithium negative electrode, the separator end can be reliably aligned. Easy to do. Furthermore, it is only necessary to straighten the end of the separator to the lithium negative electrode until at least the end of the next process (the step of forming it into a cylinder), and the lithium negative electrode and other It is sufficient that the separator does not peel off from the surface; for example, it is sufficient that the separator ends are simply covered with the negative electrode current collector.
