The vanadium electrolyte production equipment independently developed by Shenzhen ZH Energy Technology Co., Ltd. (hereinafter referred to as “ZH Energy ”) has been officially launched and delivered, providing core technological and product support for the stable operation of the customer's 60,000 cubic meter annual vanadium flow battery electrolyte production line.

As a key part of the vanadium flow battery industry chain, the stability of the vanadium electrolyte preparation process and the level of purity control directly impact the electrolyte's performance and mass production capacity. The electrochemical reduction preparation of vanadium electrolyte has three major advantages: “high purity, high precision, and zero pollution.” The system is equipped with a full - dynamic electrochemical valence regulation technology, breaking through the impurity residue and energy efficiency barriers of traditional chemical methods. This reduces vanadium ion valence error, boosts electrolyte purity, and enhances the cycle life and energy efficiency of vanadium flow batteries.

The vanadium electrolyte production equipment designed and manufactured by ZH Energy , with its advanced electrode stack and electrolyte control technology, offers a solution for large - scale vanadium electrolyte production that is both economical and reliable, boasting the following technical advantages:

- Intelligent and efficient: Full - process digital control enables real - time monitoring of electrolyte and equipment status, allowing interaction with higher - level systems for unattended operation.

- Stable performance: A custom electrode stack for electrolyte production ensures low energy consumption, no leakage, and minimal risk of deposition blockages, guaranteeing stable operation within the designed lifespan.

- Precise control: A charging control strategy developed from years of electrolyte production experience improves electrolysis speed while maintaining high energy efficiency and reducing power loss. It also offers simple one - key production settings and control operations.

- Good scalability: Modular production line design supports customized expansion of 3,000 to 60,000 cubic meters of electrolyte production per year, meeting the needs of different - sized energy storage projects.

The successful delivery of this vanadium electrolyte production equipment marks another significant step for ZH Energy in achieving autonomy in key flow battery materials. As a global leader in flow battery key material and equipment R&D and manufacturing, ZH Energy has built a comprehensive independent technology system, spanning new electrolyte R&D, non - fluorine ion membrane innovation, high - performance electrode stack production, and system integration. Since its strategic cooperation with Central South University in 2021, both parties have accelerated the R&D and industrialization of key flow battery materials. Relying on Dr. Xie Wei, ZH Energy 's chief scientist, with nearly 20 years of experience in the American flow battery field, and Professor Liu Suqin's team from Central South University, with over 20 years of research in vanadium electrolytes, they have formed a complementary advantage of “international industry experience + local basic research,” deepening collaborative industry - academia - research integration. This has injected a strong driving force into the R&D and industrialization of key materials, propelling the commercial application of China's flow battery technology.
