Committed to becoming the global in lithium battery copper foil intelligent equipment. Congratulations to KOTA Technology for winning the Gaogong Golden Globe Award

On November 16, 2022, the 2022 Gaogong Lithium Battery Annual Conference with the theme of "Thousands of New Power China the World" was successfully concluded in Shenzhen. With its advanced technical concepts and huge development potential, KOTA Technology Co., Ltd. stood out in the Gaogong Lithium Battery Golden Globe Award with the theme of " the World with Chinese Power" and won the 2022 Golden Globe Award for "Fast-Growing Enterprise". It is understood that more than 200 companies participated in this year's Golden Globe Award selection, and the companies that were finally shortlisted are the mainstays of the industry's development.

　　Mr. Mitsuya Matsuda, General Manager of KOTA Technology, was invited to attend the annual meeting and delivered a speech. General Manager Matsuda made an in-depth analysis of market development trends and technological innovations. He pointed out that with the continuous growth of market demand for lithium battery copper foil and the continuous improvement of battery companies' requirements for copper foil product performance, the core production equipment of lithium battery copper foil will also continue to be upgraded.

　　For example, from 2017 to 2019, the lithium battery copper foil industry mainly promoted cathode rollers with a diameter of 2.7 meters, and the industry is currently developing cathode rollers with a diameter of 3.6 meters. At the same current density and the same speed, the foil production efficiency of a cathode roller with a diameter of φ3.6m and the same width can be increased by about 35% compared to a cathode roller with a diameter of φ2.7m.

　　According to GGII data, China's lithium battery copper foil shipments in 2021 were 281,000 tons, a year-on-year increase of 124.4%. If lithium batteries continue to use traditional copper foil in the future, it is estimated that 1.25 million tons of copper foil will be needed by 2025, which will put great pressure on copper resource consumption.

　　If composite copper foil (PET composite copper foil, PP composite copper foil, etc.) is used, copper consumables can be reduced by about 2/3, copper resources can be better saved, and it is also better than traditional copper foil in terms of safety and energy density. KOTA Technology responded quickly to the market and accelerated the research and development of composite copper foil manufacturing equipment.

　　According to Mitsuda Mitsuya, the production of PET copper foil faces the following difficulties: , the winding system needs to ensure that the film does not wrinkle or deform during winding and unwinding and operation; second, the temperature control system of the equipment needs to achieve precise temperature control; finally, it is necessary to ensure that the composite copper foil will not be perforated.

　　In response to this, KOTA Technology adopts magnetron sputtering double-sided coating technology and completes precise control of the PET copper foil production process through modular design. It plans to complete the assembly and debugging of the prototype in early 2023, and it is expected to produce PET copper foil samples in March-April next year.

　　The large-scale expansion of domestic lithium battery copper foil production capacity has directly driven the growth of market demand for upstream copper foil production equipment, providing good development opportunities for domestic copper foil equipment companies. Facing the new changes in lithium battery copper foil, Matsuda Hikaru believes that it is necessary to cooperate with customer technology and production trends, and to make good preparations for talent reserves and accumulation of related technologies in order to win the future market.

　　In the future, KOTA Technology will continue to interpret the corporate mission of "intelligent manufacturing, customer success, and value creation" with actions, bring more professional products to the lithium battery copper foil market, and work tirelessly to become a company in new energy intelligent equipment.
