Descrizione
Ion diffusion, intercalation, adsorption and deposition dynamics under an electric field are the fundamental principles of the majority of electrochemical energy devices. Yet, the relationship between ion transport dynamics and 3D structures remains elusive.
3D-ZERO aims to visualise, understand, and manipulate ion transport dynamics and the interplay among the physicochemical properties, and untangle the complex bulk microstructural and interfacial phenomena inside electrochemical devices. 3D-ZERO will pioneer operando correlative imaging of X-ray Compton scattering–computed tomography (XCS-CT) to unravel the underlying chemical heterogeneity in 3D structures for rational design of structures, and innovate in sustainable processing to fabricate the designed structures and control ion transport kinetics.
The novel processing and correlative imaging methodologies that 3D-ZERO develops will allow the fabrication and study of a new generation “zero-excess” multivalent batteries, i.e. multivalent batteries without an anode, that will use earth-abundant elements only and achieve the ultimate highest energy densities with respect to their chemistries. To demonstrate the universality of the processing and imaging technologies, 3D-ZERO will also translate the developed understanding to make and study reversible solid oxide cells that generate green H2 and clean electrical energy reversibly. The valence electron momentum density of materials at the atomic and molecular level during redox reactions will be studied to show chemical reactivity and significantly widen the materials and ultra-light element ions, e.g. O2-, H+, that can be imaged, and the results will be superimposed to nano- and microstructures to uncover insights in 3D. The breakthroughs generated from this interdisciplinary project will benefit a wide range of disciplines beyond electrochemical energy storage and conversion, including sensors, chemistry, geophysics, biology, observation technologies, etc..
