| Povzetek: | Rechargeable alkaline batteries (RABs) represent a promising post-lithium energy storage technology owing to their intrinsic safety, use of sustainable materials, and compatibility with existing battery manufacturing infrastructure. However, their com- mercial deployment remains limited by insufficient understanding of ageing and degradation mechanisms. In this work, spec- tral X-ray micro-computed tomography (S-XμCT) is employed to non-destructively investigate pristine and aged Mn–Bi-based RABs, with the aim of resolving ageing-induced changes. A spectral photon-counting detector was used to acquire multi-energy datasets, which were then processed and decomposed into material-specific volumes corresponding to carbon, manganese, and bismuth. Stability and reproducibility testing confirmed the robustness of the S-XμCT acquisition and decomposition process. Quantitative image analysis revealed a pronounced increase in the number of clustered features in aged samples, strongly local- ized near the anode interface, with the bismuth specific volume providing improved discrimination compared to the traditional attenuation volume. These results highlight the added value of S-XμCT for material-specific, volumetric assessment of degrada- tion phenomena in rechargeable alkaline batteries and suggests its potential as a non-destructive diagnostic tool for battery ageing studies. |
