The popularity of electric vehicles and portable electronic devices, lithium battery pack the demand is increasing. In the production process of lithium battery pack, all kinds of equipment play a vital role. This article will introduce the common equipment in the production process of lithium battery pack.

1. Mixing equipment
   mixing equipment is used for mixing and homogenizing positive and negative materials. The cathode material is usually composed of metal oxide such as cobalt, nickel and manganese, while the anode material is usually composed of graphite, graphene and other materials. The mixing equipment evenly mixes various raw materials by means of rotation or stirring to ensure the uniformity and consistency of battery materials.

2. Coating equipment
   coating equipment is used for coating positive and negative materials. During the coating process, electrode slurry is applied to conductive foil or current collector to form positive and negative electrode plate. Coating equipment usually includes coating machine, drying equipment, etc., which requires precise control of coating speed, coating thickness, drying temperature and other parameters to ensure the uniformity and stability of the electrode.

3. Winding equipment
   winding equipment is used for winding assembly of positive and negative electrode electrode plate, diaphragm and electrolyte. In the winding process, it is necessary to accurately control the winding tension, winding speed and winding angle to ensure the compact and consistent structure of the battery.

4. Hot pressing equipment
   hot pressing equipment is used for hot pressing the positive and negative electrode sheet and diaphragm of the battery to ensure the compact and consistent structure inside the battery. Hot pressing equipment usually includes Hot Press, mold, etc., which requires precise control of temperature, pressure, time and other parameters to ensure hot pressing effect and battery performance stability.

5. Molding equipment
   the molding equipment is used to shape the battery, including the molding of the positive and negative shells and the integral molding of the battery pack. Molding equipment usually includes molding mold, molding machine, etc., which need to precisely control parameters such as molding temperature, pressure and time to ensure the consistency of the appearance and size of the battery.

6. Charge and discharge test equipment
   charge and discharge test equipment is used to test the performance of lithium battery pack produced, including capacity test, cycle life test, safety performance test, etc. Charge and discharge test equipment needs to accurately control parameters such as charge and discharge current, voltage and temperature.Number to ensure accurate evaluation of battery performance.

7. Safety protection equipment
   in the production process of lithium battery pack, safety protection equipment is particularly important. Including explosion-proof equipment, gas detection equipment, fire-fighting equipment, etc., are used to ensure the safety of production operators and equipment and prevent safety accidents caused by abnormal battery conditions.

The production process of lithium battery pack involves many equipments, including mixing equipment, coating equipment, winding equipment, hot pressing equipment, molding equipment, charging and discharging test equipment and safety protection equipment. These equipments play a vital role in the production process of lithium battery pack and have an important impact on the quality, performance and safety of products. With the continuous progress of science and technology, lithium battery pack production equipment will be continuously updated and upgraded to adapt to the development of new materials, new processes and new needs.
