Key aspect/summary of your research project 项目简介 全固态储能电池作为新型储能电池的重要发展方向，是实现双碳目标和新型电力系统建设，以及能源结构转型的重要技术支撑。 目前大规模应用的液态锂离子电池中， 易燃有机电解液的泄露和燃烧是导致电池安全事故的主要原因。因此，逐步将有机电解液替换为不易燃、不易泄露的固态电解质，可以有效提高锂离子电池的安全性，即便发生短路或热失控等极端情况，也可以最大程度上避免起火爆炸，实现电池的本质安全。目前，全固态锂电池还有一些科学与技术问题尚待解决，包括：高电导率、高电化学稳定固体电解质膜的规模化制备；低阻抗固固界面构筑技术；适用于固态的高比能正负极材料；固态电芯设计与综合优化方案等。围绕这些关键科学问题，本课题将主要研究高离子导电率的固态电解质、复合固态电解质膜、超薄锂金属负极、固态电池固固界面稳定性、固态电池 结构与工艺等。预期对高电导率固态电解质进行系统理论研究，制备出具有高离子电导率的固态电解质及电解质薄膜，解决固固界面接触稳定性，制备出超薄合金锂金属负极，实现具有高能量密度软包固态锂电池。 All-solid-state energy storage batteries are a key direction in the development of next-generation energy technologies. They provide critical technical support for achieving the dual-carbon goals, building new power systems, and promoting energy structure transformation. A major limitation of conventional liquid lithium-ion batteries is the risk of leakage and combustion due to flammable organic electrolytes, which frequently leads to safety incidents. Replacing these with non-flammable, leak-proof solid electrolytes significantly enhances battery safety, minimizes fire and explosion risks, and ensures intrinsic safety. However, several scientific and technical challenges remain for all-solid-state lithium batteries, including: scalable fabrication of solid electrolyte films with high ionic conductivity and electrochemical stability; low-impedance solid–solid interface engineering; development of high specific energy electrode materials suitable for solid-state systems; and integrated cell design and optimization. This project focuses on addressing these critical issues through the study of high-conductivity solid electrolytes, composite electrolyte films, ultra-thin lithium metal anodes, solid–solid interfacial stability, and advanced structural designs for solid-state batteries. The goal is to establish a theoretical framework for high-performance solid electrolytes, fabricate high-conductivity electrolyte films, resolve interfacial stability problems, develop ultra-thin alloy lithium anodes, and ultimately realize high-energy-density soft-pack solid-state lithium batteries. Other Requirements (if any): 1. The candidate should have a solid academic foundation in chemistry, materials science, energy storage, electrochemistry, or related disciplines, with particular interest in next generation battery technologies. 2. The candidate should be familiar with organic or inorganic synthesis, surface/interface engineering, or the fabrication and testing of electrochemical devices, especially lithium-based energy storage systems. 3. Familiarity with characterization techniques such as SEM, TEM, XPS, XRD, Raman, or NMR is expected. Experience in interpreting data from these methods to understand material structures and interfaces is desirable. 4. A strong motivation to pursue independent research addressing key scientific and engineering challenges in solid-state lithium battery technology. 5. Strong collaborative and communication skills are essential. The project involves joint supervision across XJTLU, XJTU, and the University of Liverpool, and may include research visits and cross-institutional collaboration 有意者请将个人简历及其他有助于申请的材料发送至 chenguang.liu02@xjtlu.edu.cn 或者 xiaogang.han@xjtu.edu.cn。 注: 不用跟帖，直接发邮件就行，主题请注明博士申请。 |
