Design of next-generation ceramic fuel cells and real-time characterization with synchrotron X-ray diffraction computed tomography

Miniaturized ceramic fuel cells are attractive for portable devices, but performance should be optimized. Here the authors report a micro-monolithic ceramic cell design for a tubular solid oxide fuel cell containing a multi-channel anode support with enhanced power density and stable operation.

Spatial quantification of dynamic inter and intra particle crystallographic heterogeneities within lithium ion electrodes

Dynamic chemical and structural heterogeneities within electrodes are known to lead to battery degradation and failure. Here, the authors show that X-ray diffraction computed tomography can be used to spatially quantify the dynamic crystallographic states of electrodes as they operate and degrade.

3D microstructure design of lithium-ion battery electrodes assisted by X-ray nano-computed tomography and modelling

The 3D microstructure of the electrode predominantly determines the electrochemical performance of Li-ion batteries. Here, the authors show that the microstructural heterogeneities lead to non-uniform Li insertion and current distribution while graded-microstructures improve the performance.

4D imaging of lithium-batteries using correlative neutron and X-ray tomography with a virtual unrolling technique

The combination of X-ray and neutron CT enables 4D studies, i.e. to explore the evolution of 3D structures with time. Here the authors apply this approach to a Li-ion primary cell, revealing elsewhere unseen trends in the spatial distribution of performance aided by a new ‘unrolling’ methodology.

High-speed 4D neutron computed tomography for quantifying water dynamics in polymer electrolyte fuel cells

Characterisation of water dynamics in polymer electrolyte fuel cells is important for technology development. Here, the authors demonstrate a 4D neutron imaging technique, enabling quantitative analysis of the local water evolution, and identify performance parameters for water management.
