Composite Materials Processing for Solid State Batteries

用于全固态电池的新型金属氧化物薄膜的合成、制备和材料加工研究。这涉及固态电解质材料的合成和化学的发展，以将其形成具有定制的孔隙率和电极界面的厚膜器件。我们使用各种技术从原子间尺度(例如X射线和中子衍射)、微观尺度(电子显微镜)到宏观尺度(表面积测量)对这些材料进行表征。这项工作的最终目标是提供一条可靠的、可扩展的路线，获得100g数量的最先进的固体电解液，使金属锂能够在所有组件都处于固态的下一代电池中安全使用。这承诺了能量密度的阶梯式变化，减少了电池体积，因此将使电动汽车的续航里程大幅增加。

Study of synthesis, preparation, and materials processing of new metal oxides films to deliver all Solid State Batteries. This involves the synthesis of solid state electrolyte materials and development of chemistry to form these into thick-film films devices with tailored porosity and electrode interfaces. We use a variety of techniques to characterise these materials over length scales from the interatomic (e.g. x-ray and neutron diffraction), microscopic (electron microscopy) up to the macro scale (surface area measurements). The ultimate aim of this work is a reliable, scalable route to >100g quantities of state-of-the-art solid electrolytes that enable the safe use of metallic lithium in next-generation battery in which all components are in the solid state. This promises a step-change in energy density, a reduction in battery volume and hence will enable large increases in the range of electric automobiles.
