Leading the Way in High-End Technology, Pioneering a Cleaner Future — Beijing Yifeng Technology Overcomes Technical Barriers in High-End Sectors and Leads the Industry Towards High-Quality Development

Ten years of unwavering dedication; pioneering breakthroughs, forging ahead in pursuit of our dreams. In 2025, Beijing Yifeng Technology celebrates its tenth anniversary. After a decade of technological refinement, market expansion and brand building, the company has achieved significant breakthroughs in the field of high-end solvent purification. It has successfully overcome core technological barriers in high-end sectors such as semiconductors and new energy, launching high-end specialised solvent purification systems. This marks a transition from ‘mid-range dominance’ to ‘high-end leadership’, guiding the domestic solvent purification industry towards high-end, intelligent and green development.

Over the past decade, Yifeng Technology has consistently prioritised R&D investment, allocating over 15% of its annual revenue to technological innovation. With cumulative R&D expenditure exceeding 100 million yuan, the company has assembled a highly skilled R&D team and established four core technological systems: adsorption purification, intelligent control, safety and explosion protection, and green regeneration. It has secured over 30 patents, placing its technical capabilities at an international standard. In 2025, the company achieved significant breakthroughs in technological research within the high-end sector, successfully launching high-end solvent purification systems for electronic and battery applications, thereby filling the gap in domestic equipment within this high-end market.

In the semiconductor sector, Yifeng Technology’s electronic-grade solvent purification system utilises nano-scale adsorption materials and precision filtration technology to reduce impurities such as metal ions and particulates in solvents to the ppb level, with moisture and oxygen content consistently reduced to below 5 ppm, meeting the stringent requirements of the G5 grade in semiconductor processes. The system has successfully entered leading semiconductor enterprises such as SMIC and TSMC, breaking the monopoly of overseas brands in the semiconductor solvent purification sector and providing vital support for the autonomy and controllability of China’s semiconductor industry.

In the new energy sector, the company has launched a battery-grade solvent purification system tailored to the purification needs of lithium-ion battery electrolytes. This system achieves ultra-low moisture control (≤3 ppm), effectively enhancing the cycle life and safety of lithium-ion batteries. It has been successfully adopted by leading new energy enterprises such as CATL and BYD, contributing to the high-quality development of the new energy industry. Furthermore, the system employs a closed-loop circulation design with a solvent recovery rate exceeding 98%, putting green and low-carbon principles into practice and delivering dual benefits in terms of economic efficiency and environmental protection.

In terms of intelligent technology, Yifeng Technology has upgraded its AI-powered control system by integrating big data and artificial intelligence technologies. This enables intelligent optimisation of equipment, fault prediction and remote diagnostics. The system can automatically adjust operating parameters based on users’ habits and experimental requirements, thereby enhancing operational efficiency and stability. Furthermore, the company has launched an intelligent management platform that facilitates centralised management and data aggregation across multiple devices, allowing users to monitor equipment status and solvent usage in real time and improving laboratory management efficiency.

To mark its tenth anniversary, Yifeng Technology hosted a celebratory event themed ‘A Decade of Purity, Leading the Future with Intelligence’, inviting industry experts, user representatives and partners to gather and reflect on the company’s ten-year journey whilst looking ahead to future directions. During the event, the company unveiled its five-year development plan, clearly stating its commitment to deepening its presence in high-end sectors, increasing R&D investment, expanding into overseas markets and establishing itself as a global provider of solvent purification solutions.

Leading the high-end sector with intelligence, creating a pure future. A decade of dedication has forged a glorious legacy; a new journey begins a fresh chapter. In 2025, taking its tenth anniversary as a new starting point, Yifeng Technology aims to achieve major breakthroughs in high-end sectors, lead industry development through technological innovation, and earn global recognition through unwavering commitment to quality, thereby contributing even more significantly to China’s scientific research innovation and industrial upgrading.
