Solid-State Electrolytes for Advanced Energy Storage

实现雄心勃勃的气候变化目标(例如清洁增长和零增长战略)要求电化学储能技术具有更高的安全性、稳定性和能量密度。固体离子导电电解液是这项任务的核心，将促进全固态电池和基于金属阳极的先进化学。然而，将足够的离子导电性与理想的加工和界面性能结合在一起的材料仍然难以捉摸。该项目的目标是：-设计新的无机系列固体电解质，包括块状(电解液)和薄膜(保护层)形式-在传统锂离子电池和超越锂离子电池的环境中测试这些组件-为这些系统开发计算模型，并使用实验数据和测量的材料性能执行验证-利用电池性能和建模结果来优化材料和器件设计-将使用X射线和中子衍射和拉曼光谱来确定结构属性。除了充放电行为外，还将使用电化学阻抗谱和循环伏安法相结合的方法来评估导电性和稳定性。使用XPS、AFM、X射线层析等对循环设备的分析将提供界面上的化学和物理洞察。首先，我们将针对使用可伸缩溶液技术合成的晶态Zintl相和氧化物薄膜。这些相对未经探索的家族具有广泛的化学可调整性，将测试先进能量存储所需的稳定离子传导固体的设计原则。-设计新的无机系列固体电解质，包括块状(电解液)和薄膜(保护层)形式-在传统锂离子电池和超越锂离子电池的情况下测试这些组件-为这些系统开发计算模型，并使用实验数据和测量的材料属性执行验证-利用电池性能和建模结果来优化材料和设备设计-结构属性将使用X射线和中子衍射和拉曼光谱来确定。除了充放电行为外，还将使用电化学阻抗谱和循环伏安法相结合的方法来评估导电性和稳定性。使用XPS、AFM、X射线层析等对循环设备的分析将提供界面上的化学和物理洞察。首先，我们将针对使用可伸缩溶液技术合成的晶态Zintl相和氧化物薄膜。这些相对未经探索的家族具有广泛的化学可调整性，将测试先进能量存储所需的稳定离子传导固体的设计原则。

Achieving ambitious climate change targets (e.g., Clean Growth and Road to Zero strategies) demands electrochemical energy storage technologies with enhanced safety, stability and energy densities. Solid ion-conducting electrolytes are central to this mission and will facilitate both all-solid-state batteries and advanced chemistries based on a metal anode. However, materials that combine sufficient ionic conductivity with desirable processing and interfacial properties remain elusive. The aims of this project are to: - Design new families of inorganic of solid-state electrolytes both in bulk (electrolyte) and thin film (protective layer) formats - Test these components in traditional and beyond Li-ion cells - Develop computational models for these systems and perform validation using experimental data and measured material properties - Utilise cell performance and modelling results to optimise material and device design Structural properties will be determined using x-ray and neutron diffraction and Raman spectroscopy. Conductivity and stability will be assessed using a combination of electrochemical impedance spectroscopy and cyclic voltammetry, in addition to charge/discharge behaviour. Analysis of cycled devices using, e.g., XPS, AFM, x-ray tomography will give chemical and physical insight at interfaces. Initially we will target crystalline Zintl phases and oxide thin films synthesized using scalable solution-based techniques. These relatively unexplored families with wide chemical tunability will function to test design principles for stable, ion-conducting solids fundamental to advanced energy storage. - Design new families of inorganic of solid-state electrolytes both in bulk (electrolyte) and thin film (protective layer) formats- Test these components in traditional and beyond Li-ion cells- Develop computational models for these systems and perform validation using experimental data and measured material properties- Utilise cell performance and modelling results to optimise material and device designStructural properties will be determined using x-ray and neutron diffraction and Raman spectroscopy.
