X-Ray Tomography of Porous, Transition Metal Oxide Based Lithium Ion Battery Electrodes



original image

Synchrotron radiation X-ray tomographic microscopy is performed on transition metal oxide-based porous electrodes to obtain statistically significant volume 3D reconstructions of the microstructure. A segmentation algorithm that allows identification of individual particles for electrochemical simulations is developed and implemented. The tomographic data (raw and processed) and the corresponding electrochemical data for 16 different cathodes is provided open source.
