The equipment can support a variety of substrates such as PET, BOPP, PI, SUS, etc. The width of the substrate supported by the equipment is 600-2000mm, the thickness of the substrate is 3-50 microns, the winding speed is 0.1-30m/min, and the tension range is 10-250N. The production line production speed exceeds 20m/min, and the PET composite copper foil can achieve 15,000m of hole-free and wrinkle-free coating, and the PP composite copper foil can achieve improved bonding strength to meet customer delivery requirements.

②eMeridian RR-R wire feeding evaporation winding coating equipment

The equipment supports the production of substrates with a width of 600-2000mm, a thickness of 4.5-50 microns, a winding speed of 0.1-100m/min, and a tension range of 10-250N.

In addition, NAURA Vacuum has combined a number of innovative technologies in the production process of composite current collectors to improve the production efficiency and product quality of composite current collectors through lean production.

① Winding roller system design and control technology:

We independently developed an intelligent winding control system (e-Web) to ensure extremely high tape running stability under efficient operation. We established a mechanical model of the winding system to analyze and optimize the roller system design; multi-stage tension control increases the compatibility of substrates and process adjustment window, and achieves stable winding and high-quality coating of different types of flexible substrates; real-time monitoring of winding speed and tension data during the winding process provides strong support for production decisions.


②Black Gold Drum Technology:

The black gold drum technology independently developed by NAURA Vacuum is used in the eMeridian RR-M series magnetron sputtering winding coating equipment and the eMeridian RR-R wire feeding evaporation winding coating equipment. This technology uses special materials to treat the surface of the coating drum, improves the bonding effect between the substrate and the coating drum, enhances the system's heat management capabilities, and ensures the quality of the film.

③ Low temperature magnetron sputtering technology:

In order to address the bottleneck problem that flexible polymer film materials are prone to thermal deformation at high temperatures, North Huachuang Vacuum has independently developed a cathode system, innovatively designed an auxiliary anode, and optimized the magnetic field distribution to achieve a highly uniform distribution of plasma, greatly reducing the surface temperature of the substrate during magnetron sputtering and improving product yield.

④Wire feeding evaporation technology:

An evaporation simulation model was established and the evaporation system was optimized and designed, which greatly improved the uniformity of the coating. A wire feeding closed-loop control module was developed, which achieved stable evaporation of the material through stable clamping control of the metal wire and real-time adjustment of the landing point and angle of the metal wire on the evaporation boat, greatly improving the uniformity of the thin film.

⑤Gas ion etching and assisted deposition technology:

It can effectively clean and etch the substrate surface, enhance the film-base bonding strength, and improve the film quality. The independently developed linear ion source has no filament and grid in the source, simple structure and long life. The source body can be fed with inert gas and reaction mixed gas, such as Ar, H2, O2 and C2H2, etc. It can not only be used as a reaction deposition source, but also can achieve auxiliary deposition, improving the film quality.

Currently, the lithium battery industry is entering a period of profound adjustment. The soaring prices of raw materials have intensified cost pressures, and cost reduction and efficiency improvement have become urgent needs for enterprises. Looking to the future, with its unique performance, composite current collectors are expected to become the standard in the lithium battery industry.



Against this backdrop, NAURA Vacuum, as a leader in the field of composite current collector equipment, is poised to take off. With its profound technical background and continuous process innovation, its equipment and technology will help lithium battery companies achieve the goal of reducing costs and increasing efficiency, and promote the lithium battery industry to develop in a more efficient, green and sustainable direction.
