Thanks to LiteScope AFM-in-SEM technology, we can analyze the properties of active materials and their interactions with other parts of the electrode and electrolyte. This technology also allows us to better understand the degradation processes of electrode materials during cycling in terms of the interaction of individual grains of polycrystalline cathode materials at submicroscopic and microscopic levels. A better understanding of the degradation processes could help to prevent it and improve of the performance of the new types of Li-ion batteries.
We have been collaborating with the Nenovision team on SSB cathode analysis and have found their technology highly valuable for assessing conductivity together with SEM imaging. The insights from conductivity measurements have been crucial in evaluating the quality of SSB electrodes and their integrity after cycling. Additionally, the detailed surface morphology analysis offered by the Litescope has enabled us to identify microstructural changes post-cycling. We are convinced that the combination of SEM and AFM provided by Nenovision's Litescope device is essential for understanding battery performance and facilitating improvements in battery technology.
The short evacuation time allows for quick and efficient sample exchanges. This minimizes downtime and ensures that samples are handled in a controlled environment, preserving their integrity and preventing contamination.
Air-sensitive samples are protected from surface contamination or oxidation in a vacuum or inert gas atmosphere at all times.
