SNE Completes World's First Fully Automated All-Vanadium Flow Battery Factory, Set for Full Production in September
SNE (Zhejiang Xingchen Xinneng Technology Co., Ltd.) has recently announced the completion of the world's first fully automated all-vanadium flow battery factory, which is expected to commence full-scale production in early September 2025.
In May 2023, SNE inaugurated its first all-vanadium flow battery gigawatt-scale factory in the Wujin National High-Tech Zone in Changzhou. In just over three months, the facility achieved gigawatt-scale production capacity, setting a new record for the fastest flow battery factory commissioning in China.
All-vanadium flow batteries represent one of the most commercially viable energy storage technologies currently available. Unlike conventional batteries, they offer high safety performance, extended operational lifespan, flexible configuration, and enable resource recycling. These batteries are well-suited as energy storage systems for clean energy sources such as wind and solar power, and can effectively smooth grid fluctuations to ensure grid stability and reliability, making them particularly ideal for long-duration, large-scale energy storage applications.
Since its establishment in 2021, SNE has been committed to the research, development, manufacturing, and production of high-performance all-vanadium flow battery energy storage systems. The company maintains comprehensive coverage across the entire value chain, including electrolytes, core stack components, complete battery systems, and energy storage solutions.
SNE's upcoming fully automated production line, the world's most advanced for flow batteries, integrates a flexible intelligent manufacturing system with a full lifecycle digital product system. The facility achieves seamless integration of intelligent production lines, warehousing, and logistics, combining intelligence, automation, and digitization to enable information traceability across the entire value chain from design and production through engineering, application, and maintenance.
In terms of lean manufacturing, SNE has meticulously deconstructed the production process to implement automated operations across die-cutting, encapsulation, stacking, pressing, fastening, and inspection. Combined with intelligent vision systems and automated inspection, the facility enables comprehensive data collection throughout the manufacturing process, enhancing both quality and efficiency.
The company has established a remote command platform that enables correlated mapping between physical production, virtual production, and digital models. This platform facilitates real-time data analysis and decision-making regarding production scheduling, equipment allocation, and quality control, improving response times to emerging issues while enabling continuous optimization and improvement of production line operations.
SNE's business presence spans the entire value chain, including stone coal vanadium mines, electrolytes, core stack components, complete battery systems, and energy storage solutions, with core technologies and materials developed entirely in-house. To ensure raw material supply security and enhance economic performance, SNE has secured upstream vanadium resources and established strategic partnerships with upstream raw material suppliers and electrolyte manufacturers. The company is developing electrolyte production facilities to achieve full integration from vanadium ore raw materials to electrolytes and ultimately to complete battery systems. Additionally, SNE offers vanadium electrolyte recycling through financial leasing arrangements, creating a closed-loop system from production through usage to recovery, thereby reducing initial project investment requirements and alleviating upfront capital pressure for customers.
