液流電池 | 研究方向

液流電池是一種透過液態電解液中活性物質的氧化還原反應來儲存與釋放電能的裝置。其最大特色在於功率與能量的容量設計可完全獨立，且具備高安全性、長循環壽命與易擴充等優勢，是極具潛力的大型電網儲能技術。其中，全釩液流電池（VRFB）因正負極皆採用釩離子，無跨膜汙染問題而備受矚目；而非水系有機液流電池（NAORFB）則可突破傳統水系電池的電壓極限，提供更高的能量密度。本實驗室近期在液流電池領域取得多項前瞻突破。在全釩液流電池方面，我們透過奈米結構工程開發出雙功能的「氮摻雜碳化鎢奈米線（N-WC NWs）」觸媒，單一材料即可同時高效催化正極與負極的氧化還原反應。同時，我們也創新提出基於金屬有機骨架（MOF）前驅物的「鎢酸化鋯觸媒」，藉由生成穩定的 W-O-Zr 化學鍵結，顯著增強了活性組分與基底間的結合力，有效解決電解液沖刷導致活性物質脫落的問題，大幅提升了電池的能量效率與高電流密度下的穩定性。在系統工程端，團隊首創「束繩捆綁」封裝技術，成功開發出體積縮減約 66% 的 5 kW 級高功率國產化電堆。在非水系有機液流電池方面，我們透過分子工程設計出「N-異丁基吩噻嗪（iBuPT）」，利用立體障礙效應有效穩定自由基陽離子，成功將電池開路電壓提升至 2.25 V，解決了有機體系循環壽命短的痛點。
