Detailed Introduction: Enerflow Technology Co., LTD was founded in February 2022, with a registered capital of 112.59 million RMB. It is a high-tech enterprise integrating R&D, production, sales, and operation of flow battery systems. The company is dedicated to providing safe, durable, long-duration, and environmentally friendly energy storage solutions.
Enerflow places high importance on building a strong talent pool and advancing technology. It is the only company that holds core technologies for both all-vanadium and iron-chromium flow battery systems, with independent production capabilities for key components such as battery stacks and electrolytes. The company has obtained 28 patents related to battery stack structures, materials, and electrolytes, including 18 invention patents, 4 utility model patents, and 6 design patents. Additionally, 2 more invention patents are under substantive examination, with more than 50 unpublished and pending patent applications, including vanadium purification technology.
Enerflow's independently developed hydrochloric acid-based all-vanadium redox flow battery system is the world’s first. It offers high energy density, high conductivity, low temperature control costs, and low material costs. For the first time in China, the system uses a water-based hydrochloric acid electrolyte, which significantly improves vanadium ion solubility, increases energy density by 25%, and reduces the required storage tank volume by 15-18%. System pump consumption is reduced by more than 20% compared to mainstream all-vanadium flow battery systems under the same operating conditions. By adopting independently developed electrolyte technology, the operating temperature range of the electrolyte has been expanded from 0-40°C to -35°C~65°C, reducing the cost of temperature control systems, improving system efficiency, and ensuring reliable energy supply under extreme weather conditions. The company has also developed its own porous ion membrane, which completely replaces perfluorosulfonic acid proton exchange membranes, reducing costs by 95%. The system's charge-discharge cycle life exceeds 20,000 cycles, ensuring long service life. Power and capacity units can be decoupled to meet various application needs. The electrolyte and system materials are 100% recyclable, and the water-based electrolyte is intrinsically safe, with no fire or explosion risks, significantly enhancing environmental sustainability.
