Description

Technical Field

[0001] The utility model relates to the field of lithium battery tab processing, and in particular to a positioning plate for a lithium battery tab. Background Art

[0002] Tabs are a raw material for lithium-ion polymer battery products. For example, mobile phone batteries, Bluetooth batteries, laptop batteries, etc. that we use in our daily lives all need tabs. Batteries have positive and negative poles, and tabs are the metal conductors that lead the positive and negative poles out of the battery cell. In layman's terms, the tabs on the positive and negative poles of the battery are the contact points during charging and discharging.

[0003] In the lithium battery industry, the tab, as the conductive part of the battery cell, plays a crucial role in cell quality. During the production of the electrode, before the tab and the electrode are welded together, a protective tape is applied to the tab head 1-2mm from the edge of the electrode. This acts as an insulator and prevents short circuits between the tab and the steel shell. To prevent short circuits in the battery tab, the exposed portion of the tab is pre-coated before welding. However, existing automatic tab-coating systems for battery tabs still have some shortcomings, hindering the industry's development. Currently, lithium battery positioning can easily damage the battery and lead to inaccurate tab positioning. The tape application is inefficient, difficult to operate on a small adhesive surface, and expensive.
