ENERFLOW Technology's "Electric Internal Circulation" Continuous Electrolyte Technology Invention Patent Authorized

Recently, ENERFLOW Technology's independently developed invention patent for "a method of continuous production of all vanadium electrolyte based on internal circulation reduction" was authorized (patent number: ZL 2025 1 1438043.2), marking ENERFLOW 's first continuous production line for electrolyte that has been put into operation in the industry, and building a complete intellectual property barrier from principle to process.

Traditionally, vanadium electrolyte production relies on batch processes that require the continuous addition of solid reducing agents, resulting in high costs, impurity risks, and price volatility. The core of this patent lies in the pioneering technology of "electric circulation reduction", which fundamentally reconstructs this path. The technology creates a highly efficient internal circulation system within the production process: it no longer relies on external addition of reducing agents, but instead regenerates some electrolyte products into low-priced reducing agents through electrolysis and feeds them back to the reaction front in real time. This has achieved a fundamental leap from "external addition" to "system self-sufficiency", laying the foundation for true continuous and automated production.

Principle innovation directly translates into significant economic and engineering benefits. According to calculations, on a production line with an annual output of 36000 cubic meters, this technology can save 2-3 million yuan in reducing agent costs annually and generate significant energy-saving benefits. At the same time, through optimized processes and proprietary equipment design, the patent system solves the industry problem of intermediate products easily causing blockages, ensuring stable operation of the entire process.
