Problems solved by technology
In the manufacturing process of traditional lithium batteries, the raw materials of the pole piece are first baked, and then the sheet production operation is performed, and then the pole piece obtained by the production is wound to form a core, and then packaged and sealed, baked and injected in sequence. Liquid and other operations, so that the number of baking operations of the lithium battery is more, the corresponding baking process is more, so that the lithium battery manufacturing device occupies a larger space, and at the same time makes the effect of removing moisture from the lithium battery poor.

Embodiment Construction
[0042] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0043] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention provides a lithium battery and manufacturing equipment and method of the lithium battery. The manufacturing method of the lithium battery comprises the following steps: fixing and shaping the pole piece group and the diaphragm to form a battery cell; carrying out baking operation on the battery cell; carrying out packaging and film sealing operation on the baked battery cell and the aluminum-plastic film shell to form a battery cell one-sealing structure; performing liquid injection operation on the packaged and film-sealed battery cell one-sealing structure; wherein the baking operation, the packaging and film sealing operation and the liquid injection operation are carried out in the same negative pressure environment. Due to the fact that the pole piece set and the diaphragm are fixed and shaped, the diaphragm exists between the positive pole piece and the negative pole piece, then baking operation is conducted, the evaporation speed of water on the pole pieces is high, the baking efficiency is improved, due to the fact that baking operation does not need to be conducted after coating and film sealing operation of the manufacturing method of the lithium battery, and the packaging procedure of the lithium battery is simplified. And therefore, the space occupied by the lithium battery manufacturing equipment is small, and the problem that the lithium battery manufacturing equipment occupies a large space is solved.
Description
technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery, lithium battery manufacturing equipment and a method. Background technique [0002] With the continuous development and progress of society and the continuous improvement of people's living standards, the demand for electronic products continues to increase, and the corresponding demand for lithium batteries also continues to increase. In the manufacturing process of traditional lithium batteries, the raw materials of the pole piece are first baked, and then the sheet production operation is performed, and then the pole piece obtained by the production is wound to form a core, and then packaged and sealed, baked and injected in sequence. Liquid and other operations, so that the number of baking operations of the lithium battery is more, the corresponding baking process is more, so that the lithium battery manufacturing device occupies a larger space, ...
