研究方向
本課題組致力於氫能技術、電化學能源技術和功能材料的研發與套用
1. 液流電池
液流電池是一種新型的使用液態“燃料” 的電化學能量轉換裝置。它的輸出功率取決於電堆的大小和數量,而儲能容量則取決於液態“能量液”(即電解液)的體積和濃度。因此,液流電池的規模設計非常靈活。相對於市場上常見的鋰離子電池及實驗室研究較多的鋰硫及鋅空電池等,這種液流電池更適合於大容量儲能領域。它的未來發展空間廣闊,將是可再生能源、智慧型電網、電動汽車(液態“能量液”替代汽油)、網際網路+、智慧能源的重要組成部分。但是,相對商用的鋰離子電池來說,傳統液流電池的能量密度較低。同時,目前絕大部分的液流電池使用有毒及腐蝕性強的“能量液”。因此,本課題組將會致力於開發清潔高效的新一代液流電池,探索其工作機理,並實現其套用價值。
2. 鋰/鈉離子電池及其產品設計
“搖椅式”的鋰/鈉離子電池憑藉其優異的循環性能,較高的比容量和能量密度,成為了在攜帶型電子設備、電動汽車等多種關鍵領域套用的能源設備首選。然而,為了滿足未來的套用需求,此類電池的能量密度、快充性能、安全性和成本價格還需要進一步的最佳化。同時針對下一代智慧型套用,此類電池的下一代產品還需要設計成具備柔性、可穿戴性及透明性。因此,本課題組將會致力於研發一系列的相關重要部件套用於高性能的下一代鋰/鈉離子電池。
3. 酸鹼電池(酸鹼濃差電池)
工業生產中殘留的廢酸廢鹼一直是環境污染處理裡面的一個重要問題,如何有效科學地處理這些腐蝕性強的廢物是一個很有價值的研究課題。酸鹼作為發電儲能活性物質在世界上一直處於初級研究階段,僅有少數研究組在進行相關研究。因此,廢酸廢鹼一直都沒有被人們視為可以被廣泛利用的“能量”物質。本課題組將會在相關研究基礎下繼續探索及開發具備套用價值的酸鹼電池或酸鹼電化學裝置。
4. 燃料電池
燃料電池是一種電化學的發電裝置,可直接將化學能轉化為電能,能量轉化效率高,且無污染。各類燃料電池(例如氫燃料電池及直接醇類燃料電池)在未來的能源市場上仍然極其重要。同時,合理使用高效的燃料電池有利於保護環境和資源。但是,市售燃料電池的電極及隔膜材料成本過高,導致普及套用仍有一定困難。由於燃料電池與液流電池的電堆結構相似,這將會有利於本課題組同時研發適合於燃料電池與液流電池的實用價廉的複合電極材料、電化學催化劑和隔膜材料。
5. 金屬電池
金屬電池主要是指以電極電位較負的金屬如鋰、鈉、鉀、鋅、鎂、鋁等作為負極的一類電池。其中,金屬空氣電池(以空氣中的氧或純氧作為正極的活性物質,例如鋰-空氣電池)和金屬硫電池(以單質硫作為正極的活性物質,例如鋰-硫電池)具有很高的比能量和能量轉換效率。因此,它們都是非常高效的能量存儲體系。但是,此類電池的商業化套用仍存在一些技術問題尚待解決(例如金屬枝晶所引起的安全隱患及電池容量衰減等)。本課題組將會通過最佳化電池部件(例如電極材料及電解液)並系統研究其工作機理,找出切實可行的方法來進一步推動此類電池的商業化進程。
6. 光伏電池系統及電池產品規模化
二次電池與光伏電池一體化相結合的電力系統既可以在高峰時期有效地減少電網負荷,又將有望作為獨立的“物聯網”攜帶型電子設備的電力來源。顯然,設計整合鈣鈦礦或有機太陽能電池與本課題組研發出的各種二次電池(例如液流電池、鋰/鈉離子電池和鋰-硫電池等)是一個重要的研究課題。同時,本課題組會從防水防火防爆等安全性能方面進一步完善光伏電池系統的一體化設計整合。另外,本課題組會與工業界緊密合作,從而推動電池產品規模化生產及套用。
7. 功能材料
功能材料對於能源、醫療、工業和航空等技術領域至關重要。本課題組致力於開發與研究新型功能材料,其套用領域包括能源轉換與儲存(例如電池及電容器)、電磁禁止、光電催化(例如水分解及二氧化碳還原)、工業催化和生物醫藥等。具體研究內容為:(i)利用先進的製備合成方法開發碳材料(例如石墨烯、納米管和納米孔碳)、二維過渡金屬碳化物和氮化物(MXenes)材料、金屬氧化物等及它們的複合材料;(ii)利用多種加工成型方法如層層自組裝、噴墨印刷等進一步最佳化性能和製備功能器件;(iii)對功能材料及其器件進行深入表征和套用基礎研究;(iv)與工業界緊密合作,推動新材料的商業套用進程。
8. 功能有機分子材料
有機分子材料的套用領域廣泛,一般分為有機高分子材料(例如聚噻吩及聚四氟乙烯)與有機小分子材料(例如2,6-二羥基蒽醌及三硫二丙烯)。本課題組將以套用為導向,合成製備及最佳化此類有機材料,並通過深入研究機理作用探索有機分子結構(或官能團)與材料性能的關係,積極推進新型有機分子材料的生產及套用。
