3. Lithium battery pasting barley paper machine

This step requires the use of batteries to automatically paste barley paper machine, and some bosses may ask why they need to paste barley paper on lithium batteries? In fact, barley paper is very important in electronic products, and the barley paper is pasted at the positive electrode of the battery to prevent the positive electrode from colliding with the positive electrode, resulting in a short circuit or dust entering the gap. Highland barley paper has good insulation, water resistance and abrasion resistance.

Fourth, lithium battery spot welding machine

The lithium battery spot welding machine is to assemble a single cell into a battery pack through nickel chip spot welding.

5. Comprehensive tester for finished products

Finished batteries need to be inspected for production, so a comprehensive tester for finished products is used.

6. Aging test of finished products

This requires the use of battery aging cabinets and battery aging meters.

The above is the relevant process flow of pack equipment required to open a lithium battery assembly plant.

and the introduction of the required equipment, I hope it can help you.

<>1. Lithium battery MES production control.

The MES system will be connected to digital management from the incoming material management of upstream manufacturers of lithium batteries, so as to realize the batch management of battery cells, wiring harnesses, flat tubes, boxes, and BMS monitoring boards.

In the production process of the MES system, the single cell is first tested strictly for items such as voltage, resistance, and capacitance, so as to realize the connection between the MES system and the cell testing equipment, and record and feedback the detection situation in real time.

In the process of cell grouping, a plurality of single cells will be combined in series to form a module, at this time, the MES system associates the coding of all single cells to a module according to the requirements of the assembly process, forming a corresponding association of the code, and then the MES system automatically generates and prints the module barcode, and gives the barcode to the module.

During the module assembly process, the MES system will error-proof, bind, and process control the materials used in the module, and the key materials such as wiring harnesses and pole pieces used on the module are bound to the module code. After the module is assembled, the MES system will test the module for differential pressure, temperature, humidity and other items.

In pack**, the MES system combines multiple modules into a single box, and also records key material codes such as module codes and BMS monitoring boards in real time, and strictly monitors the screw torque during the assembly process.

After the PACK assembly is completed, the quality of the entire lithium battery pack will be checked through various tests, such as insulation withstand voltage test, electrical performance test, air tightness test, EOL test, etc., and the MES system is connected with the current testing equipment to control and read the detection status and test data in real time.

After all assembly and inspection tests are completed, the MES system generates the pack barcode and automatically triggers the barcode printer to print the barcode, at this time, a complete lithium battery finished product is manufactured and officially rolled off the production line.

2. Summary. In summary, we can see the important position of the MES system in the whole lithium battery production process and the penetration ability of the MES system in the lithium battery production process. MES system combined with TS16949 standard, in the production of lithium battery emphasis is on the production of fine management and digital control, in the production process in a visual way to present the key data, MES system will realize lithium battery from the material batch, process technology, quality control, sales and delivery, market application and other dimensions of digital management, improve production efficiency, improve product quality, to achieve full traceability.

The above is just a symbolic introduction to the MES system, the core management business in the back-end PACK production process of lithium batteries.

There are a lot of lithium battery production equipment, lithium battery from the large process, one is to produce lithium cells, the other is to package the battery cells as finished lithium batteries (also known as pack), if you do the second kind, you can consider buying lithium batteries, and then process them into finished lithium batteries, with less investment. If you make lithium battery cells, there are many processes, starting from the procurement of raw materials, which are divided into the main processes such as slurry stirring, coating, barbecue, slitting, filming, winding, shelling, liquid injection, sealing, formation, etc., with a large investment.

The main automatic assembly equipment and procedures of lithium battery pack (pack) are as follows:

There are hundreds of domestic lithium battery automatic equipment manufacturers, but there are few with an output value of more than 100 million yuan. The relatively large Wuxi pilot, the first share of lithium battery equipment, the leading enterprise, the equipment positioning in the high-end, the customers are basically battery giants. YH Technology is also a listed company, and its strength is also relatively strong.

There are also Xinjiatuo, Yakang, Han's Laser, etc. With the rise of the lithium battery industry, domestic equipment enterprises have also continued to grow.

Lithium batteries are produced in Jiangsu, Guangzhou and other places.

New energy is the biggest highlight of Jiangsu's industrial investment this year, especially in the field of lithium batteries for new energy vehicles, Jiangsu Province has become the world's largest lithium battery manufacturing base, driven by strong investment, Jiangsu's energy industry will grow by more than 40% in 2022, becoming the power source of steady growth.

Lithium batteries can be broadly divided into two categories, lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain lithium in a metallic state and are rechargeable. The fifth-generation product of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate and performance** ratio are better than those of lithium-ion batteries.

R&D value

Lithium metal batteries generally use manganese dioxide as the cathode material, lithium metal or its alloy metal as the anode material, and use non-aqueous electrolyte solution. Lithium-ion batteries are generally batteries that use lithium alloy metal oxide as the cathode material, graphite as the anode material, and non-aqueous electrolyte. Graphite is mostly used as the anode material.

In addition, lithium metal, lithium alloy, silicon carbon anode, oxide anode material, etc. can also be used for anode.

In order to develop varieties with better performance, various materials are being researched to create products that have never been seen before. In 1992, Sony successfully developed lithium-ion batteries, and its practical application greatly reduced the weight and volume of portable electronic devices such as mobile devices, notebooks, and calculators.
