In the wave of high-quality development in the new energy lithium-ion battery industry, anode materials, as the core carrier of energy storage in lithium batteries, have a metal impurity content that directly impacts the risk of internal short circuits and thermal runaway safety hazards. This is a critical indicator determining battery life and safety. The industry demands efficient and precise control of metal impurities throughout the entire production process of anode materials. As a leading enterprise that has consistently ranked first in global anode material shipments for fifteen consecutive years, BTR's business covers a full range of products including natural graphite, artificial graphite, and silicon-based anodes, with a global production capacity exceeding 570,000 tons. Its products are widely supplied to leading battery companies at home and abroad. This large-scale global layout demands higher standards for quality assurance in metal impurity control. Recently, BTR officially purchased Infinitum cleanliness testers, which will be fully applied to the metal impurity detection process of anode materials at all its production bases, building a core defense line for the quality of high-end anode materials.

The fast scanning speed and precise measurement are the core performance reasons why BTR chose Infinitum, and are also key advantages that meet the needs of anode material metal impurity control. The Infinitum cleanliness tester is equipped with a customized high-speed scanning module and metal-specific identification algorithm, achieving a dual breakthrough in detection 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. This perfectly matches BTR's batch testing rhythm for its 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 impurities above 5μm, effectively distinguishing various high-risk conductive metal impurities such as iron, copper, and nickel. The detection error is strictly controlled within 2%, and the detection data conforms to authoritative lithium-ion battery industry standards such as GB/T 24533-2019, providing reliable data support for anode material quality control and avoiding battery safety risks caused by metal impurities from the source.

Prompt service response is another important factor that earned Infinitum BTR's favor. In response to BTR's global layout covering multiple regions in China and overseas bases in Indonesia, Morocco, and other countries, Infiro has established a dedicated service team and built a rapid response service system throughout the entire process: In the initial stage, they respond to requests within 12 hours, conduct on-site investigations at various production bases domestically and internationally, and customize personalized metal foreign object detection solutions based on the production processes of different products such as natural graphite and silicon-based anodes; 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 multilingual one-on-one specialized operation training to ensure that operators at home and abroad can quickly get started; in the later stage, they provide a 24/7 technical support hotline and establish a regular cross-border inspection mechanism, ensuring that equipment failures are responded to within 2 hours and resolved within 24 hours, comprehensively guaranteeing the stable and efficient operation of equipment at all global bases and providing continuous service support for metal foreign object control throughout BTR's entire production process.

This cooperation with BTR is a significant breakthrough for Infiro's cleanliness testing instruments in the global high-end manufacturing field of anode materials, fully demonstrating the precise adaptability of its product performance and service system to the needs of large-scale, globalized production in the industry. In the future, Infiro will continue to focus on the pain points of metal foreign object control in lithium-ion battery anode materials, iterate and upgrade equipment technology and service response mechanisms, and provide more leading lithium-ion battery material companies with efficient, accurate, and reliable cleanliness testing solutions, contributing to the high-quality development of the new energy lithium-ion battery industry.
