- 摘要
- 釩電池儲能系統具備高安全性、長循環壽命及可大規模彈性擴充的特性，已成為能源轉型與再 生能源併網中重要的長時間儲能技術之一。然而，電解液製備成本占比高且資源限制，成為推廣應 用的關鍵瓶頸。本研究提出並驗證一項已獲得發明專利保護的電化學還原技術，作為釩電解液再生 與循環利用之解決方案。本技術以電解法直接將五價釩離子還原為四價或三價態，避免化學還原法 中衍生副產物問題。 使用回收釩資源作為原料，經電解還原製得電解液，經分析結果顯示，再生電解液在導電度、 氧化還原活性及長循環穩定性方面，均與商用電解液相當，且製程可望降低整體電解液成本之潛 力，主要是無須還原劑和二次廢液處理等。此外，電解技術具備模組化擴充，可應用於產業生產電 解液製程使用。 本研究之貢獻在於：第一，提出一種經專利驗證之創新電解技術，為釩電解液再生提供具可行 性的解決方案；第二，將電解液回收再利用與循環經濟理念結合，凸顯儲能系統永續應用之價值； 第三，驗證再生電解液之性能，確立其在釩液流電池中的應用可行性。不僅具備學術價值，亦展現 實務應用與技術轉移潛力，對未來大規模儲能系統的推廣具有關鍵意義，並展現了釩電池在循環經 濟與能源永續發展中的戰略價值。

- Vanadium redox flow batteries (VRFBs) have emerged as one of the most promising long-duration energy storage technologies for integrating renewable energies, owing to their high safety, long cycle life, and flexible scalability. However, the high cost and limited availability of vanadium electrolytes remain major barriers to commercialization. This study presents and validates a patented electrochemical reduction process which provides a sustainable and economically viable approach for vanadium electrolyte regeneration. Unlike conventional chemical reduction methods that employ SO2, metal powders, or oxalates and produce secondary wastes, the patented process directly reduces V5+ to V4+/V3+ ions through electrolysis, thereby eliminating hazardous by-products and minimizing environmental impact. Recycled vanadium resources were used as raw materials for electrolyte regeneration via electrochemical reduction. The regenerated electrolytes exhibited comparable conductivity, redox activity, and long-term cycling stability to commercial electrolytes. Moreover, the process has the potential to reduce overall production costs primarily by eliminating chemical reductants and secondary waste treatment steps. The modular design of the electrolytic system also enhances its industrial scalability. The contributions of this work are threefold: (i) it proposes an innovative, patented electrochemical regeneration process for vanadium electrolytes; (ii) it integrates electrolyte recycling with the concept of a circular economy, highlighting the sustainability of VRFB applications; and (iii) it experimentally verifies the electrochemical performance of regenerated electrolytes, confirming their feasibility for flow battery systems. This patented process not only demonstrates academic significance but also highlights its industrial applicability and potential for large-scale commercialization of VRFB systems.
