He has published over 200 SCI papers, with total citations exceeding 14,000 and an H-index of 66, and holds multiple granted patents. He has received the Cambridge Entrepreneurs Association top prize and the Dow Sustainability Innovation Award (sole grand prize). In this project, he will provide critical theoretical support and experimental guidance for electrochemical analysis and kinetic decoupling studies at composite heterointerfaces. Dr. Fred Blanc (UoL Supervisor): Dr. Blanc is a Professor in the Department of Chemistry at the University of Liverpool. He obtained his PhD in Chemistry in 2008 from the Université de Lyon. His research focuses on the development and application of solid-state NMR spectroscopy to investigate atomic-scale structure, dynamics, and disorder in functional materials for energy storage, conversion, and catalysis. He has published extensively on understanding ion transport pathways and material failure mechanisms. Prof. Blanc has received numerous prestigious awards, including the 2025 Dalton Horizon Prize from the Royal Society of Chemistry, and has held major fellowships such as the Marie Curie Research Fellow and the Leverhulme Trust Fellowship. He will contribute expertise in advanced magnetic resonance characterization to probe the structural evolution and dynamics of the composite electrode material. 丁萌博士（西交利物浦大学）：西交利物浦大学副教授、博士生导师，她于新加坡科技设计大学获得本科及博士学位。于新加坡国立大学从事博士后研究，专注于二维材料组装及其在能源存储器件和电化学海水淡化中的应用。2021年获新加坡国家化学学会Prof. Lee Soo Ying青年化学家银奖，2023年入选姑苏创新创业领军人才。迄今发表文章50篇，H因子30，总引用超3500次。她将提供材料合成和电容去离子脱盐的主要指导。 丁理峰博士（西交利物浦大学）：西交利物浦大学化学与材料科学系代理系主任、高级副教授，自2013年起任职于西交利物浦大学。此前，他曾任英国萨里大学玛丽·居里研究员，并于英国莱斯特大学获得博士学位。丁博士的研究聚焦于利用分子模拟和人工智能技术研究和设计新型材料，旨在从分子层面深入理解现有及理论预测材料的结构与性能关系，推动面向能源存储、气体/液体分离与检测、同位素分离及可生物降解聚合物等应用领域的新材料理性设计。迄今已在Science、Chem、Nature Communications等顶级期刊发表高质量论文60余篇。在本项目中，他将利用分子模拟和AI技术为复合电极材料的设计优化及离子选择性机理的理解提供理论计算支持。 郗凯教授（西安交通大学）：西安交通大学教授、博士生导师，储能材料与器件教育部工程中心副主任，国家级高层次人才。获英国剑桥大学博士学位，曾任剑桥大学石墨烯能源研究组负责人及副研究员，长期专注于高比能二次电池研究。迄今发表SCI论文200余篇，总引用超14,000次，H因子66，并获授权多项发明专利。曾获剑桥企业家协会创业大赛最高奖及陶氏化学可持续发展创新奖（唯一大奖）。在本项目中，他将为复合异质界面的电化学分析及动力学解耦研究提供关键理论支持与实验指导。 Fred Blanc博士（利物浦大学）：英国利物浦大学化学系教授。2008年于里昂大学获化学博士学位。研究方向主要为开发和应用固态核磁共振（NMR）波谱技术，从原子尺度研究功能材料的结构、动力学和无序性，应用于能源存储、转化及催化等领域。他在离子传输路径和材料失效机理研究方面发表了大量成果。Blanc教授曾获英国皇家化学会2025年Dalton Horizon Prize等多项重要奖项，并获玛丽·居里学者、Leverhulme Trust等多项基金资助。他将为本项目贡献先进磁共振表征技术，用于探测复合电极材料的结构演变与动力学行为。 Key aspect/summary of your research project 项目简介 The global transition to sustainable energy has driven an ever-growing demand for lithium, while spent lithium-ion batteries represent a rich urban mine of lithium resources. Efficient recovery of lithium from these wastes is critical for resource recycling and supply chain security. However, the leachate from spent batteries contains numerous competing ions (e.g., Ni2+, Co2+, Mn2+), making selective lithium separation extremely challenging. This project aims to develop a novel electrochemical lithium recovery technology based on a LiCoMnO4/MXene composite electrode, enabling highly selective extraction of lithium ions from spent battery leachate. The research will address four core scientific questions: 1) How MXene surface terminations influence the local electric field and the desolvation energy barrier of Li+; 2) The respective contributions of capacitive-controlled and diffusion-controlled processes to the selective extraction mechanism; 3) The dynamic response of the LiCoMnO4 lattice to Li+ intercalation under MXene buffering and its effect on structural fatigue over cycling; and 4) The physical/chemical mechanism by which the composite rejects high-valence competing ions in complex environments. The research integrates precision synthesis, advanced electrochemical analysis (CV, EIS), in-situ synchrotron characterization, and Density Functional Theory calculations to elucidate the selective separation mechanism at the atomic scale. The successful implementation of this project will provide a novel technological pathway and theoretical foundation for the efficient and green recovery of lithium from spent battery resources. 全球向可持续能源转型对锂资源的需求日益增长，而废旧锂离子电池中蕴藏着丰富的锂资源，其高效回收对于实现资源循环利用和保障供应链安全至关重要。然而，废旧电池浸出液中存在大量竞争离子（如Ni2+、Co2+、Mn2+等），使得锂的选择性分离极具挑战。本项目旨在开发一种基于LiCoMnO4/MXene复合电极的新型电化学提锂技术，实现从废旧电池浸出液中对锂离子的高选择性回收。 研究将聚焦于四个核心科学问题： 1）MXene表面官能团对局部电场及锂离子去溶剂化能垒的影响机制； 2）电容控制与扩散控制过程在选择性提锂中的各自贡献； 3）MXene缓冲下LiCoMnO4晶格对锂离子嵌入的动态响应及其对循环结构疲劳的影响； 4）复合材料在高竞争离子环境中排斥高价态离子的物理/化学机制。 研究方案融合了高精度材料合成、先进电化学分析（CV、EIS）和原位同步辐射表征，并将实验结果与密度泛函理论计算相关联，从原子尺度揭示选择性分离机理。本项目的成功实施将为废旧电池锂资源的高效绿色回收提供新的技术路径和理论支撑。 Other preferred qualification and skill set of the candidate 对项目候选人的其他学术背景及技能要求 A strong background in electrochemistry, materials science, or a related field is desirable. Experience with nanomaterial synthesis and electrochemical characterization (e.g., Cyclic Voltammetry, EIS) is advantageous. 对项目候选人的其他学术背景及技能要求： 具备电化学、材料科学或相关领域的扎实背景。有纳米材料合成和电化学表征（如循环伏安法、EIS）经验者优先。 有意者请将个人简历及其他有助于申请的材料发送至 meng.ding@xjtlu.edu.cn 注: 不用跟帖，直接发邮件就行，主题请注明博士申请。 |
