The birth of a power battery usually requires three major process links: front, middle and rear, each link contains multiple subdivided processes. Among them, the core link of the front-end process is coating, that is, the stirred slurry is uniformly applied on the metal foil and dried to make positive and negative electrode sheets; the core link of the middle-end process is winding/lamination, that is, the positive and negative electrode sheets and the diaphragm are wound/laminated to form a battery cell in a certain order; the core link of the rear-end process is melting and capacitance, with the purpose of completing the activation and detection of the battery cell.

Accordingly, a battery production line also needs to include multiple subdivided equipment. Generally speaking, the equipment value of the front, middle and rear process links account for 35%, 35%, and 30%, respectively. Among them, the value of the coating machine in the front process is about 80%, the value of the winding/lamination machine in the middle process is about 70%, and the value of the chemical component capacitance equipment in the back process is about 30%. Lithium battery equipment is a non-standard product, and suppliers need to design, develop and produce according to customer requirements.

After years of development, domestic lithium battery equipment companies have continuously increased their market share with higher service quality, faster response speed and stronger cost advantages. In 2019, the domestic production rate of lithium battery equipment in the Chinese market has reached 90%.

In addition, laser technology has become an indispensable tool for battery production due to its high efficiency, precision, flexibility, reliability and stability, small welding material loss, automation and high safety. Its welding, cutting, compliance, and cleaning functions play an important role in the front, middle and rear channels. Thanks to the prosperity of the new energy track, many laser companies may have deepened or increased their investment in the field of lithium battery equipment, becoming important upstream suppliers of power batteries and their equipment manufacturers.

In addition, key equipment such as cathode rollers with high technical difficulties have also broken the foreign technology monopoly in recent years and opened the road of domestic substitution. Lithium battery copper foil equipment is another key equipment in the battery industry chain. In addition to the mainstream electrolytic copper foil, the advantages of PET composite copper foil are considered to be a strong competitor of lithium battery copper foil based on cost, process, performance, etc. The key production links magnetron sputtering and water electroplating equipment are gradually emerging.

This article will sort out the domestic suppliers of lithium-ion battery manufacturing equipment, including front, middle and rear equipment, laser equipment and lithium battery copper foil equipment manufacturers. It should be noted that the sorting of laser equipment and copper foil equipment manufacturers mainly covers related companies in the lithium battery field, and industry giants such as Dier Laser that have not yet been involved in the lithium battery field have not been sorted out in this time.

Overall, the battery production equipment industry has high barriers and customized characteristics. On the one hand, the high barriers are due to technical accumulation. Suppliers with stronger technical capabilities have more advantages in terms of security, consistency, automation, etc.; on the other hand, the "3331" collection model commonly used in the industry leads to a longer payment cycle, which puts higher requirements on the supplier's financial strength. The high degree of customization of non-standard products has made the battery production equipment industry a relatively high link in the power battery industry chain with relatively high gross profit margin and customer stickiness. As the power battery market concentration is getting higher and higher, the in-depth binding of high-quality downstream customers has also become a key factor in gaining competitive advantages.

At present, battery production equipment has achieved a domestic production rate of 90% in the domestic market, and the development degree and competitive landscape of each sub-sector are different.The domestic production rate of front-end process equipment has reached 85%, but there is still a gap between domestic equipment and international advanced level; the domestic equipment in the middle process has a competitive advantage compared with international equipment, among which the market concentration of core equipment winders is relatively high, the market share of pilot intelligence exceeds 50%, and the market concentration of lamination machines is relatively low; the product competitiveness and market concentration of domestic equipment in the later process are also relatively high, and domestic equipment has entered the overseas supply chain.

In contrast, the laser equipment industry is relatively scattered, and there are advantageous enterprises in various sub-sectors such as welding, cutting, and marking. The competitive landscape of the lithium battery copper foil equipment industry is relatively clear. Currently, there are three main domestic cathode roller suppliers, and PET composite copper foil equipment is still in the stage of domestic substitution.

Looking at the development history of the battery production equipment industry, we will see the process and trends from domestic substitution to export overseas, from stand-alone supply to full-line delivery, from automation to intelligence. With the continuous evolution of the development stage of the new energy industry, equipment suppliers will also gradually move further and further on the road to reducing costs and increasing efficiency.
