Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production and processing, in particular to a lithium battery core winding device. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have now become mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable.

[0003] In the process of lithium battery production and processing, the lithium battery wire needs to be wound. The existing lithium battery cell winding device has some shortcomings during use. For example, when winding the battery cell, different sizes of battery cells require winding rollers of different sizes for winding, resulting in the waste of winding rollers and the increase of the cost of battery cell winding. At the same time, it is easy to accumulate during the winding process, resulting in uneven winding. For this reason, we propose a new type of lithium battery cell winding device.
