Automation Equipment for Solid-state Lithium Battery Production
The
equipment used to produce cylindrical battery is processed, tested and packaged
separately. In the process of battery turnover, it is bound to cause the
increase of labor cost and low production efficiency.
The
utility model overcomes the disadvantages of the technology, and provides an
automatic device for producing cylindrical battery with low labor cost and high
production efficiency.
The
utility model relates to an automatic equipment for producing cylindrical
battery, an automatic production line of solid-state lithium-ion battery, which
is a full-automatic production line of round solid-state battery, and the whole
process is completed in a glove box, ensuring that the whole process is
produced in an oxygen free and water-free environment, and ensuring the quality
of the product.
In
order to ensure the accuracy of positive material, solid electrolyte and
negative material, the process features are as follows:
1.
Powder injection of positive material
The
key point is to use the spiral powder injection method with vibration, so that
the positive material powder is not in the whole powder injection process, and
no residue is attached to the pipe wall, ensuring the accuracy of the positive
material powder injection.
2.
Solid electrolyte powder injection
It
uses high temperature to melt the solid electrolyte first, then high
temperature to inject liquid, which ensures the accuracy of powder injection.
3.
Powder injection of negative material
It
is also to melt the anode material first, and then inject liquid at high
temperature to ensure the accuracy of powder injection of the anode material.
