The project aims at the preparation of artificial composite materials with mixed ionic and electronic conducting properties, which are of great interest for many applications in the field of energy storage and energy conversion. The composites are prepared by the deposition of an electron-conductor on the surface of porous oxides, which conduct oxygen ions or lithium ions by means of atomic layer deposition. The mixed-conducting composites are characterized by a high number of electron-conductor/ion-conductor interfaces, which can have a tremendous influence on charge transport and charge storage in the material system. In the project, the properties of the electron-conductor/ion-conductor interfaces are therefore comprehensively characterized and their impact on the transport and storage properties of the composites in examined. The project aims at a detailed understanding of the influence of the interfaces on the electrochemical properties of the composite materials in order to use these interface effects specifically for the development of electrochemical components for energy applications.

该项目旨在制备具有混合离子和电子导电性能的人造复合材料，这对能量储存和能量转换领域的许多应用都非常重要。该复合材料通过在多孔氧化物表面沉积电子导体来制备，所述多孔氧化物通过原子层沉积来传导氧离子或锂离子。混合导电复合材料的特征在于大量的电子-导体/离子-导体界面，其可以对材料系统中的电荷传输和电荷存储产生巨大影响。因此，在该项目中，电子导体/离子导体界面的特性得到了全面的表征，并研究了它们对复合材料的传输和存储特性的影响。该项目旨在详细了解界面对复合材料电化学性能的影响，以便将这些界面效应专门用于开发用于能源应用的电化学组件。
