In the wave of high-quality development in the new energy lithium battery industry, anode materials, as the core carrier of energy storage in lithium batteries, have their metal and fiber impurity content directly related to the risk of internal short circuits and cycle life, making them a key indicator determining battery safety performance. Fiber impurities, in particular, are more difficult to detect due to their similar acoustic characteristics to the material itself, becoming a pain point in industry control. As a leading enterprise ranking among the top four globally in artificial graphite anode shipments and the world's number one in anode shipments for commercial vehicle power batteries, Kaijin New Energy's business covers a full range of anode products, including artificial graphite, silicon-based materials, and energy storage hard carbon, with a global production capacity exceeding 120,000 tons. Its products are widely supplied to leading battery companies at home and abroad, such as CATL and BYD, and its large-scale global layout demands higher standards for impurity control. Recently, Kaijin New Energy officially purchased Infiro cleanliness testing instruments, which will be fully applied to the impurity detection process at all its production bases, strengthening the quality defense line for high-end anode materials.
The precise adaptation to the dual control needs of metal and fiber impurities is the core reason why Kaijin New Energy chose Infiro. The Infiro cleanliness testing instrument is equipped with a customized high-speed scanning module and a dual-impurity intelligent recognition algorithm, achieving a double breakthrough in efficiency and accuracy: the single-sample scanning and detection time is only 3 minutes, an improvement of more than 30% compared to similar equipment in the industry, perfectly matching the batch testing rhythm of Kaijin New Energy's tens of thousands of tons of anode material production capacity, significantly reducing the impact of the testing process on production flow; in terms of measurement accuracy, it can accurately capture tiny metal and fiber impurities above 5μm, effectively distinguishing various high-risk conductive metal impurities such as iron, copper, and nickel, and solving the problem of fiber impurity detection. The detection error is strictly controlled within 2%, and the detection data conforms to authoritative standards in the lithium battery industry, providing reliable data support for anode material quality control and avoiding battery safety risks caused by dual impurities from the source.

Rapid service response and adaptability to a global layout are another important factor in Infiro winning Kaijin New Energy's favor. Given Kaijin New Energy's layout across multiple regions in China, including Zhejiang, Qinghai, and Guizhou, as well as its overseas planned bases, Infiro has assembled a dedicated service team and established a rapid response service system throughout the entire process: In the initial stage, they respond to requests within 12 hours, conduct on-site surveys at various production bases within China, and customize personalized dual foreign object detection solutions based on the production processes of different products such as artificial graphite and silicon-based materials; in the intermediate stage, they simultaneously install and debug multiple sets of equipment, committing to completing the installation and commissioning of all equipment within 48 hours, and providing one-on-one specialized operation training to ensure operators can quickly master the equipment; in the later stage, they provide a 24/7 technical support hotline and establish a regular inspection mechanism, ensuring equipment malfunctions are responded to within 2 hours and resolved within 24 hours, comprehensively guaranteeing the stable and efficient operation of equipment at all bases, and providing continuous service support for foreign object control throughout Kaijin New Energy's entire production process.

This collaboration with Kaijin New Energy represents a significant breakthrough for Infiro's cleanliness testing instruments in the field of dual foreign object control for negative electrode materials, fully demonstrating the precise adaptability of its product performance and service system to the needs of large-scale production in the industry. In the future, Infiro will continue to focus on the pain points of foreign object control in lithium-ion battery negative electrode materials, iterating and upgrading its dual foreign object detection technology and service response mechanisms, providing efficient, accurate, and reliable cleanliness testing solutions for more leading lithium-ion battery material companies, and contributing to the high-quality development of the new energy lithium-ion battery industry.
