围绕“双碳”重大战略决策,我校化学与化工学院刘淑玲教授、王超副教授和仝建波教授聚焦电化学储能器件与转化及其关键材料研究,并在该领域取得了系列研究进展。近2年来在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)等国际权威刊物上发表论文20多篇,主要研究成果介绍如下:

【成果1】全固态锂金属电池的锂离子交换驱动界面缓冲层

本工作利用PEO基质中的Li+-H+离子交换化学构建有机/无机PEO/HMO界面化学层策略来解决ASSLMBs界面不稳定面临的重大挑战。超薄(≈104 nm)高性能缓冲层不仅提供了高离子电导率、足够的Li+迁移通道,LMO还拥有源自HMO的快速锂离子交换能力。PEO/HMO层的高离子电导率使得LFP阴极的高比容量为161.9 mAhg-1,而高负载NCM811阴极的高比容量为183.6 mAhg-1,具有良好的倍率性能。该成果发表在《Advanced Functional Materials》期刊上。

【成果2】构建磷化镍/氢氧化铁纳米异质结构用于析氧反应

本工作通过先低温溶剂热磷化,然后常温水溶液浸渍相结合的策略,制备了一种Ni2P/Fe(O)OH异质结构纳米颗粒。泡沫镍(NF)负载的Ni2P/Fe(O)OH不仅在1 M KOH中,10 mA cm-2 OER电流密度下表现出240 mV的过电位,而且Ni2P/Fe(O)OH/NF对OER也表现出优异的长期耐久性。本工作还对OER活性增强的原因进行了研究。该成果发表在《Nano Energy》期刊上。

【成果3】超低扩散势垒的四甲基铵阳离子插层MnO2用于高性能水系锌离子电池

本工作合成了具有较大层间距(0.96 nm)和超低Zn2+扩散势垒的TMA-MnO2,展示了其作为水系锌离子电池正极材料的潜力。通过四甲基铵离子TMA+和H2O分子的共同预嵌入,TMA-MnO2呈现出独特的层状结构,且层间距扩大至0.96 nm。DFT计算证实TMA+的存在降低了Zn2+扩散势垒,提高了离子电导率,从而提高了整体电池性能。在电化学测试中,TMA-MnO2 在电流密度为0.2 A g-1时比容量为310.3 mAh g-1,在2 A g-1电流密度下经过1000次循环后,容量保持率为91%。该成果发表在《Journal of Materials Chemistry A》期刊上。

【成果4】泡沫镍上生长的硒化铁/磷化钴异质结构薄膜用于析氧反应

本工作首先采用一步液相法在泡沫镍NF上生长Co2P纳米晶,然后在 Co2P/NF 上电沉积非晶态 FeSe 层。在催化碱性溶液中的OER时,FeSe/Co2P/NF在10 mA cm?2电流密度下表现出240 mV的过电位,Tafel 斜率为 65.6 mV dec?1。优异的性能来自于异质结构引起的电荷重新分布改变了羟基的吸附能,并导致更温和的 OER 动力学,表现为电荷转移阻力降低、塔菲尔斜率降低和表观活化能降低。该成果发表在《Journal of Materials Chemistry A》期刊上。

【成果5】一步磷化金属有机骨架制备铁掺杂磷化钴纳米线用于析氧反应

本工作通过一步液相法磷化含Fe2+的钴金属有机骨架,制备铁掺杂磷化钴(CoFeP)纳米线。样品呈现Co2P相,但Co和Fe之间存在明显的电子相互作用。CoFeP纳米线负载在镍泡沫(NF)上催化碱性溶液中的OER时,在10 mA cm?2电流密度下表现出240 mV的过电位,远低于Co2P/NF。动力学分析表明,晶格氧氧化机制发生在 CoFeP/NF 表面,而吸附质析出机制在 Co2P/NF 表面占主导地位。该成果发表在《Green Chemistry》期刊上。

【成果6】增强电化学性能的钴掺杂氧化锰用于水性锌离子电池正极材料

本工作通过CoMn甘油酸酯前驱体合成了钴掺杂Mn2O3,并将其应用于水性锌离子电池。钴掺杂提高了Mn2O3的离子电导率,加快了Zn2+和H+的扩散速度,从而提高了电化学性能。Co-Mn2O3在0.2 A g-1下表现出 289.7 mAh g-1的高比容量,并且在 2 A g-1下经过1000次循环后容量保持率为 84.6%。原位表征技术验证了Zn2+ 和H+共插层机制,同时阐明了Mn2O3在充放电循环过程中的形态和结构变化。该成果发表在《Green Chemistry》期刊上。
