れている。The present invention improves the reliability of the battery and reduces the cost by forming a coating layer of insulating paint over the entire circumference of the positive and negative electrodes in a battery equipped with a lead that serves as an external terminal on the positive or negative electrode. 0 [Conventional technology] It is aimed at reducing the amount of water and simplifying the manufacturing process. It has become widely used as a memory backup power supply where long-term reliability is a prerequisite. With the diversification of the uses of these batteries, for example, batteries with lead bodies are being supplied in which the positive electrode and the negative electrode are provided with lead bodies serving as external terminals.

を密着させて事故を防止する必要がある。By the way, batteries with lead bodies have excellent characteristics as a backup power source, but since the lead bodies are attached to both poles, they may come into contact with other batteries, especially when transporting the battery. There is a high possibility that it will come into contact with its own opposite pole, and accidents are likely to occur. Therefore, to prevent accidents, it is necessary to apply insulating material tightly around the entire circumference of the battery, enveloping the positive and negative electrodes.

費が非常に高くなり電池価格に対して大きな比重を占め
てしまう。Conventionally, an insulating coated tube such as vinyl chloride has been used as the above-mentioned insulating material. However, when coated tube material is used, battery manufacturing processes such as winding, welding, and heat shrinkage of the coated tube material around the battery are required, and the processing cost is high relative to the price of the battery. I don't like it because it takes up too much space. Furthermore, when trying to make the tube material thinner when insulating using coated tubes,
Particularly, breakage occurs at the corners of the battery, making it difficult to ensure desired insulation properties, and furthermore, it becomes necessary to use a protective thin film or the like. In addition, small electrical equipment,
Due to the progress in weight reduction, there is a demand for smaller and thinner button-type batteries.If tube material is used as the insulation material for such small and thinner batteries, the automatic covering equipment currently used However, automatic coating equipment specifically designed for small, thin batteries is required. When a tube material is used as an insulating material in this way, the process becomes complicated and the processing cost becomes extremely high, which accounts for a large percentage of the battery price.

対して加工費が大きな比重を占めてしまっていた。[Problems to be solved by the invention] As described above, in conventional lead-equipped batteries, a covering tube is tightly attached around the battery in order to obtain insulation, but the covering process is complicated, and the In order to respond to smaller and thinner batteries, new capital investment was required, and processing costs accounted for a large proportion of the battery price.
