Sumitomo Electric's latest VRFB technology has achieved breakthroughs in multiple key areas. Firstly, the energy density has increased by 15%, allowing for storage of more energy in the same volume, effectively reducing equipment footprint and improving space utilization. Secondly, by optimizing system design, improving electrolyte circulation control, and enhancing manufacturing processes, the system achieved a 30% cost reduction, significantly improving its economy and making it more competitive in large-scale energy storage projects. In addition, the service life of the new generation VRFB can reach 30 years, far exceeding traditional energy storage batteries, reducing operating costs throughout the entire lifecycle and improving investment return.

During the conference, Sumitomo Electric showcased practical applications of VRFB and detailed its technological advantages in the field of Long Term Energy Storage (LDES). VRFB has become an ideal choice for renewable energy storage such as wind and photovoltaic due to its high safety, long cycle life, deep discharge capability, and resistance to decay. Compared with lithium batteries, VRFB can provide a more stable energy storage solution, especially suitable for applications such as power grid peak and frequency regulation, industrial microgrids, and backup power sources for large data centers.

Sumitomo Electric announced that it will officially accept orders for the new generation VRFB in 2025 and will continue to deepen technological innovation to promote the development of global clean energy storage. As a company with decades of experience in vanadium flow battery research and development, Sumitomo Electric is accelerating the deployment of the long-term energy storage market, using technological innovation to assist in the global energy structure transformation, and contributing to the construction of a more sustainable and stable future energy system.
