Description

また、コイン型電池などにおいても、別部品として端子を取り付けることは一般的に行われているが、特に薄いことを特徴として開発されてきている薄形電池においては、端子を設けるにあたっては、例えば、特開平６―３４９４７９号公報の様に別部品として電池形成後に取り付けるか、例えば、特公平３―１９６６８号公報の様に集電体が端子を兼ねる構造としたものがある。しかし、前者の方法では、端子を取り付けることにより電池総厚さが増加し、特に厚さを制限することを目的とする薄形電池においては体積効率を下げるなどの問題があるため、後者が一般的に採用されている。薄形電池の製造方法として後者を採用した場合、正極と負極を別々に打ち抜いて張り合わせる方法では、正負極を張り合わせる際の位置合わせが困難であり、生産性も悪いため、連続的ウェブ状の正極と負極を張り合わせ、その後に電池の形に打ち抜く方法が一般的である。 Also, in a coin-type battery or the like, it is common to attach a terminal as a separate component. However, in a thin battery that has been developed with a particularly thin feature, or attached after the battery is formed as a separate part as in JP-a-6-349479 discloses, for example, there is a current collector as in JP equitable 3-19668 has a structure that also serves as a terminal. However, in the former method, the total thickness of the battery is increased by attaching terminals, and there is a problem such as lowering the volume efficiency in a thin battery intended to limit the thickness. Has been adopted. When the latter is adopted as a method for manufacturing a thin battery, the method of punching and bonding the positive electrode and the negative electrode separately makes it difficult to align the positive and negative electrodes, and the productivity is poor. In general, the positive electrode and the negative electrode are bonded together and then punched into a battery shape.
