Sunrise Granted Patent for Global Leading AI-Driven Multivariable Particle Size Control System, Marking a Major Technological Innovation in Graphite Micro-Powder Manufacturing
DOVER, USA, Oct. 22, 2025 (GLOBE NEWSWIRE) -- Sunrise New Energy Co., Ltd. (“Sunrise,” the “Company,” “we,” or “our”) (NASDAQ: EPOW) today announced that its subsidiary has been granted a global leading technological innovation patent titled “A Multivariable Particle Size Control System for Manufacturing Graphite Micro-Powder” (Authorization No. CN221619715U). This breakthrough represents one of the world’s most advanced applications of AI-based multivariable control technology in the graphite anode materials manufacturing process, further reinforcing Sunrise’s leadership in intelligent and sustainable production.
The patented system addresses a critical challenge in graphite micro-powder production—achieving precise particle size control during grinding and granulation. Traditional processes often suffer from high waste rates, inconsistent particle distribution, and excessive power consumption.
Through AI algorithms, real-time data acquisition, and multivariable discrete control, the system leverages Sunrise’s long-term production database to create an intelligent closed-loop optimization mechanism. It dynamically adjusts key variables such as blade rotation speed and fan separation rate, minimizing waste and ensuring the production line operates at its most efficient state.
By combining AI, big data, and automation, this globally leading system enhances material utilization, energy efficiency, and product quality—paving the way for a smarter, greener, and more sustainable anode material industry.
“AI-driven precision control represents a global frontier in advanced manufacturing,” said Haiping Hu, CEO of Sunrise. “This invention exemplifies Sunrise’s commitment to global technological innovation and intelligent industrial transformation.”
