Advanced visualization and analysis

Avizo Software is the solution of choice

Thanks to advanced image processing and segmentation techniques, Avizo Software makes it possible to extract key quantitative parameters of the microstructure and macrostructure of the involved materials.

At the macro level, Avizo Software can be used to assess the quality of the manufacturing process, looking into packaging, checking solder points, and detecting possible leakage or porosity and delamination. It can also examine the aging process, looking into foil, cathode and anode morphological changes or core leakage.

At the microscopic level, Avizo Software allows for the estimation of the tortuosity and permeability of the porosity structure of electrode and separator; thus, effective transport parameters  can be further used in the electrochemical performance simulation. Quantification of triple phase boundary (TPB), phase distribution and connectivity further allows for characterization of the cell’s performance.

Applications and Use cases

Performance, cost and safety are now the main factors driving ongoing battery research, with variations in battery chemistry enhancing performance at a lower cost with increased safety. Direct observation, down to the micro-scale, can be a significant benefit in the research and development of batteries and fuel cells. By combining techniques such as X-ray tomography, transmission electron microscopy (TEM) as well as focused ion beam scanning transmission microscopy (FIB-SEM) or plasma FIB (PFIB), images of the whole assembly can be obtained and observed at a variety of scales.
