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.

研究新型金属氧化物薄膜的合成，制备和材料加工，以提供所有固态电池。这涉及固态电解质材料的合成和化学发展，以将这些材料形成具有定制孔隙率和电极界面的厚膜薄膜器件。我们使用各种技术来测量这些材料的长度尺度，从原子间（例如X射线和中子衍射），微观（电子显微镜）到宏观尺度（表面积测量）。这项工作的最终目标是提供一种可靠的、可扩展的路线，以生产> 100 g的最先进的固体电解质，从而使金属锂能够安全地用于下一代电池，其中所有组件都处于固态。这有望实现能量密度的阶跃变化，减少电池体积，从而使电动汽车的续航里程大幅增加。
