porosity, thickness and mass loading) for different applications 8, 9, 10. Comprehensive understanding of the physical and electrochemical processes at the micro-scale is critical to rationalise the microstructural engineering strategy (e.g. LiB electrodes exhibit complex interplay between multiple electrochemically coupled transport processes, which rely upon the microstructure of the constituent phases and their spatial arrangement 5, 6, 7. The first challenge this work will address is elucidating the optimum electrode design for specific operating conditions. However, major challenges in safety, energy and power density, cost and durability of LIBs remain 2, 3, 4: this study aims to provide prospective solutions to these challenges. Lithium-ion batteries (LiBs) are the leading energy storage technology for portable electronics and electric vehicles (EVs) 1, which could alleviate reliance on fossil fuels. To guide manufacturing of electrode architectures, in-situ X-ray CT is shown to reliably reveal the porosity and tortuosity changes with incremental calendering steps.

Building on these insights, we propose and compare potential graded-microstructure designs for next-generation battery electrodes. The elongated shape and wide size distribution of the active particles not only affect the lithium-ion transport but also lead to a heterogeneous current distribution and non-uniform lithiation between particles and along the through-thickness direction. This elucidates how LiB performance is markedly affected by microstructural heterogeneities, particularly under high rate conditions.

Here we have developed a full microstructure-resolved 3D model using a novel X-ray nano-computed tomography (CT) dual-scan superimposition technique that captures features of the carbon-binder domain.

Driving range and fast charge capability of electric vehicles are heavily dependent on the 3D microstructure of lithium-ion batteries (LiBs) and substantial fundamental research is required to optimise electrode design for specific operating conditions.
