Tabs are a component of soft-pack lithium-ion battery products. Batteries are divided into positive and negative electrodes, and tabs are metal conductors that lead the positive and negative electrodes out of the battery, which is also the contact point when the battery is charged and discharged.<\/p>\n

The tabs can be divided into single-pole tabs, bipolar tabs\/multi-pole tabs and full-pole tabs.<\/p>\n

1. Single-pole lug: Generally speaking, small batteries have one positive lug and one negative lug, each with a lug extending out to conduct current.<\/p>\n

2. Bipolar tabs\/multi-pole tabs: If only one tab is used, the charge and discharge of current will cause excessive internal resistance, which can easily lead to various safety problems. Therefore, the current batteries gradually adopt bipolar tabs or even multi-pole tabs. For example, during the lamination process, each layer of tabs has one tab.<\/p>\n

3. Full-electrode tabs: At present, domestic cylindrical batteries have formed two mainstream full-electrode tab forms: soft connection and hard connection. Soft connection means that there is a section of the pole tab on the collector plate connected to the shell, while hard connection means "no pole tab".<\/p>\n
