圍繞“雙碳”重大戰略決策，我?；瘜W與化工學院劉淑玲教授、王超副教授和仝建波教授聚焦電化學儲能器件與轉化及其關鍵材料研究，并在該領域取得了系列研究進展。近2年來在Advanced Functional Materials（IF=18.5）、Nano Energy（IF=16.8）、Green Chemistry（IF=9.3）、Journal of Colloid And Interface Science（IF=9.4）、Journal of Materials Chemistry A（IF=10.7）等國際權威刊物上發表論文20多篇，主要研究成果介紹如下:

【成果1】全固態鋰金屬電池的鋰離子交換驅動界面緩沖層

本工作利用PEO基質中的Li⁺-H⁺離子交換化學構建有機/無機PEO/HMO界面化學層策略來解決ASSLMBs界面不穩定面臨的重大挑戰。超薄（≈104 nm）高性能緩沖層不僅提供了高離子電導率、足夠的Li+遷移通道，LMO還擁有源自HMO的快速鋰離子交換能力。PEO/HMO層的高離子電導率使得LFP陰極的高比容量為161.9 mAhg^-1，而高負載NCM811陰極的高比容量為183.6 mAhg^-1，具有良好的倍率性能。該成果發表在《Advanced Functional Materials》期刊上。

【成果2】構建磷化鎳/氫氧化鐵納米異質結構用于析氧反應

本工作通過先低溫溶劑熱磷化，然后常溫水溶液浸漬相結合的策略，制備了一種Ni₂P/Fe(O)OH異質結構納米顆粒。泡沫鎳（NF）負載的Ni₂P/Fe(O)OH不僅在1 M KOH中，10 mA cm^-2 OER電流密度下表現出240 mV的過電位，而且Ni₂P/Fe(O)OH/NF對OER也表現出優異的長期耐久性。本工作還對OER活性增強的原因進行了研究。該成果發表在《Nano Energy》期刊上。

【成果3】超低擴散勢壘的四甲基銨陽離子插層MnO₂用于高性能水系鋅離子電池

本工作合成了具有較大層間距（0.96 nm）和超低Zn²⁺擴散勢壘的TMA-MnO₂，展示了其作為水系鋅離子電池正極材料的潛力。通過四甲基銨離子TMA⁺和H₂O分子的共同預嵌入，TMA-MnO₂呈現出獨特的層狀結構，且層間距擴大至0.96 nm。DFT計算證實TMA⁺的存在降低了Zn²⁺擴散勢壘，提高了離子電導率，從而提高了整體電池性能。在電化學測試中，TMA-MnO₂ 在電流密度為0.2 A g^-1時比容量為310.3 mAh g^-1，在2 A g^-1電流密度下經過1000次循環后，容量保持率為91%。該成果發表在《Journal of Materials Chemistry A》期刊上。

【成果4】泡沫鎳上生長的硒化鐵/磷化鈷異質結構薄膜用于析氧反應

本工作首先采用一步液相法在泡沫鎳NF上生長Co₂P納米晶，然后在 Co₂P/NF 上電沉積非晶態 FeSe 層。在催化堿性溶液中的OER時，FeSe/Co₂P/NF在10 mA cm^?2電流密度下表現出240 mV的過電位，Tafel 斜率為 65.6 mV dec^?1。優異的性能來自于異質結構引起的電荷重新分布改變了羥基的吸附能，并導致更溫和的 OER 動力學，表現為電荷轉移阻力降低、塔菲爾斜率降低和表觀活化能降低。該成果發表在《Journal of Materials Chemistry A》期刊上。

【成果5】一步磷化金屬有機骨架制備鐵摻雜磷化鈷納米線用于析氧反應

本工作通過一步液相法磷化含Fe²⁺的鈷金屬有機骨架，制備鐵摻雜磷化鈷(CoFeP)納米線。樣品呈現Co₂P相，但Co和Fe之間存在明顯的電子相互作用。CoFeP納米線負載在鎳泡沫(NF)上催化堿性溶液中的OER時，在10 mA cm^?2電流密度下表現出240 mV的過電位，遠低于Co₂P/NF。動力學分析表明，晶格氧氧化機制發生在 CoFeP/NF 表面，而吸附質析出機制在 Co₂P/NF 表面占主導地位。該成果發表在《Green Chemistry》期刊上。

【成果6】增強電化學性能的鈷摻雜氧化錳用于水性鋅離子電池正極材料

本工作通過CoMn甘油酸酯前驅體合成了鈷摻雜Mn₂O₃，并將其應用于水性鋅離子電池。鈷摻雜提高了Mn₂O₃的離子電導率，加快了Zn²⁺和H⁺的擴散速度，從而提高了電化學性能。Co-Mn₂O₃在0.2 A g^-1下表現出 289.7 mAh g^-1的高比容量，并且在 2 A g^-1下經過1000次循環后容量保持率為 84.6%。原位表征技術驗證了Zn²⁺ 和H⁺共插層機制，同時闡明了Mn₂O₃在充放電循環過程中的形態和結構變化。該成果發表在《Green Chemistry》期刊上。
