化工學院劉淑玲教授團隊在電化學儲能領(lǐng)域取得重要進展

圍繞“雙碳”重大戰(zhàn)略決策，我校化學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(zhuǎn)化及其關(guān)鍵材料研究，并在該領(lǐng)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(quán)威刊物上發(fā)表論文20多篇，主要研究成果介紹如下:

【成果1】全固態(tài)鋰金屬電池的鋰離子交換驅(qū)動界面緩沖層

本工作利用PEO基質(zhì)中的Li⁺-H⁺離子交換化學構(gòu)建有機/無機PEO/HMO界面化學層策略來解決ASSLMBs界面不穩(wěn)定面臨的重大挑戰(zhàn)。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(fā)表在《Advanced Functional Materials》期刊上。

【成果2】構(gòu)建磷化鎳/氫氧化鐵納米異質(zhì)結(jié)構(gòu)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(jié)合的策略，制備了一種Ni₂P/Fe(O)OH異質(zhì)結(jié)構(gòu)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(xiàn)出240 mV的過電位，而且Ni₂P/Fe(O)OH/NF對OER也表現(xiàn)出優(yōu)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(fā)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(xiàn)出獨特的層狀結(jié)構(gòu)，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(jīng)過1000次循環(huán)后，容量保持率為91%。該成果發(fā)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(zhì)結(jié)構(gòu)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(tài) FeSe 層。在催化堿性溶液中的OER時，F(xiàn)eSe/Co₂P/NF在10 mA cm^?2電流密度下表現(xiàn)出240 mV的過電位，Tafel 斜率為 65.6 mV dec^?1。優(yōu)異的性能來自于異質(zhì)結(jié)構(gòu)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(xiàn)為電荷轉(zhuǎn)移阻力降低、塔菲爾斜率降低和表觀活化能降低。該成果發(fā)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F(xiàn)e²⁺的鈷金屬有機骨架，制備鐵摻雜磷化鈷(CoFeP)納米線。樣品呈現(xiàn)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(xiàn)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(fā)生在 CoFeP/NF 表面，而吸附質(zhì)析出機制在 Co₂P/NF 表面占主導地位。該成果發(fā)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(qū)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(xiàn)出 289.7 mAh g^-1的高比容量，并且在 2 A g^-1下經(jīng)過1000次循環(huán)后容量保持率為 84.6%。原位表征技術(shù)驗證了Zn²⁺ 和H⁺共插層機制，同時闡明了Mn₂O₃在充放電循環(huán)過程中的形態(tài)和結(jié)構(gòu)變化。該成果發(fā)表在《Green Chemistry》期刊上。
