圍繞“雙碳”重大戰(zhàn)略決策，我校化學(xué)與化工學(xué)院劉淑玲教授、王超副教授和仝建波教授聚焦電化學(xué)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(jìn)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(xué)構(gòu)建有機(jī)/無機(jī)PEO/HMO界面化學(xué)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(dǎo)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(dǎo)率使得LFP陰極的高比容量為161.9 mAhg-1，而高負(fù)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(yīng)
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(fù)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(qiáng)的原因進(jìn)行了研究。該成果發(fā)表在《Nano Energy》期刊上。
【成果3】超低擴(kuò)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(kuò)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(yù)嵌入，TMA-MnO2呈現(xiàn)出獨(dú)特的層狀結(jié)構(gòu)，且層間距擴(kuò)大至0.96 nm。DFT計算證實(shí)TMA+的存在降低了Zn2+擴(kuò)散勢壘，提高了離子電導(dǎo)率，從而提高了整體電池性能。在電化學(xué)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(yīng)
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(dǎo)致更溫和的 OER 動力學(xué)，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(jī)骨架制備鐵摻雜磷化鈷納米線用于析氧反應(yīng)
本工作通過一步液相法磷化含F(xiàn)e2+的鈷金屬有機(jī)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(fù)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(yuǎn)低于Co2P/NF。動力學(xué)分析表明，晶格氧氧化機(jī)制發(fā)生在 CoFeP/NF 表面，而吸附質(zhì)析出機(jī)制在 Co2P/NF 表面占主導(dǎo)地位。該成果發(fā)表在《Green Chemistry》期刊上。
【成果6】增強(qiáng)電化學(xué)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(yīng)用于水性鋅離子電池。鈷摻雜提高了Mn2O3的離子電導(dǎo)率，加快了Zn2+和H+的擴(kuò)散速度，從而提高了電化學(xué)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(jī)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。
