Innovation opportunities under the demand for lithium battery equipment exceeding 300 billion yuan

In the next few years, the lithium battery industry will enter the TWh era. The production capacity plans of global battery giants have reached several thousand GWh. By then, the demand for equipment will usher in a blowout. According to research by Zheshang Securities, the global energy storage + power lithium battery equipment market is expected to exceed 300 billion yuan in 2025.

In order to seize the market high ground, global mainstream battery companies including CATL, BYD, LG New Energy, Panasonic, Guoxuan, Yiwei Lithium Energy, etc. have staged a technological innovation competition to compete with each other, "Eight Immortals crossing the sea, each showing his magical powers." At the same time, the application of new battery technologies has also placed increasingly stringent requirements on production and manufacturing processes.

For example, currently all mainstream battery companies have process technology roadmaps for laminated batteries. CITIC Securities pointed out that compared with winding, the lamination process can better improve battery performance and has advantages in energy density, safety, cycle life and other aspects. With the trend of large-scale prismatic batteries and the advancement of lamination equipment technology, the lamination process is expected to be applied on a large scale.

"The future development direction of stacking machines will be all-in-one cutting and stacking machines." He Lin, chairman of Everbright Laser, made a judgment. He pointed out that the all-in-one cutting and stacking machine has the characteristics of no heavy sheets, only slight powder loss, high efficiency, and low equipment investment cost. With advantages such as small footprint and small footprint, it is expected to become the mainstream application in the future market.

According to Battery China, Everbright Laser’s innovative high-speed cutting and stacking machine realizes the integration of slicing and lamination, greatly reducing material transfer. The equipment is compact, easy to operate and maintain, and has high cost performance; its lamination efficiency is as high as 0.1- 0.15s/pcs, 400-600ppm, leading the industry. For example: 590 battery cells, 0.14s/pcs; 390 battery cells, 0.11s/pcs; 340AH battery cells, 0.12s/pcs; 640AH battery cells, 0.18s/pcs.

It is particularly worth mentioning that the multi-chip Z-type laminating machine launched by Everbright Laser adopts the method of increasing the number of laminations (2-N wafers), which is more convenient to improve efficiency, and multi-chip stacks are coated at the same time. Compared with single-chip The Z-shaped lamination reduces the wrinkles produced by the diaphragm and further improves the lamination efficiency; the integrated laser static cutting of the tabs solves the pain point of turning high tabs and improves the forming accuracy of the pole pieces; efficient automation reduces labor costs and achieves multiple goals with one stone have to.

In addition to high-speed cutting and stacking machines, Everbright Laser relies on its years of application experience in the middle section of battery cells and the module Pack section. It also sells complete sets of equipment such as laser tab cutting machines, battery core assembly lines, and module/PACK lines in large quantities.

As early as 2017, Everbright Laser launched the first zero-waste edge laser tab cutting machine in China. At that time, the cutting speed reached 60m/min, and now it has reached 120m/min, leading the industry in efficiency. The equipment has small burrs (longitudinal ≤ 7um, transverse ≤ 15um); small thermal influence range (≤ 50 um); a variety of dust removal and dust prevention methods to reduce dust diffusion.

It is understood that the battery cell assembly line equipment launched by Everbright Laser has high production line efficiency, with a square shape of 8-40ppm; high product yield, 99.8%; stable equipment operation, high utilization rate; high degree of automation and fewer operators. The module/Pack line launched has 12-40ppm for square and 12-36ppm for soft packages; the yield rate is 99.8%; the equipment operates stably and can achieve unmanned operation.

Founded in 2003, Everbright Laser is committed to the R&D, production and sales of lasers and intelligent equipment. It is a leader in the intelligent equipment industry and provides one-stop intelligent manufacturing solutions for industries such as new energy and consumer electronics. Through continuous technological innovation, the company has greatly improved delivery efficiency and cost-effectiveness of customer production line investments, and has established in-depth cooperation with domestic and foreign leading power and energy storage battery companies.

From November 28th to 30th, the 8th Power Battery Application International Summit (CBIS2023) will be held in Shanghai, China. On the afternoon of November 28, at the special themed forum titled "Innovation Stimulates Endogenous Power of the Industry" sponsored by Everbright Laser, the person in charge of Shenzhen Everbright Laser Technology Co., Ltd. will be invited to attend the meeting and deliver a speech with the theme of "Technology empowers lithium battery industry". Please pay attention to the speech "Battery Core Intelligent Manufacturing".
