Lithium ion batteries (LIB) have had a remarkable effect on the adoption of portable electronic devices. Owing to research on new materials, LIBs and advanced energy storage will play a key role in the future of energy. The LIB positive electrode class LMR-NMC (lithium- and manganese-rich, nickel manganese cobalt oxides), represents a leap forward for cathode materials if the high reaction potentials and high energies can be stabilized during cycling. Our focus is on understanding the degradation mechanisms related to phase change that happens with the charging and discharging within LMR-NMC cathode material. In this work we have used combination of X-ray and electron microscopy to probe these materials and combine the information from different modalities by developing a universal computational toolbox. We will present our results on merging and analyzing the data from 3D tomographic reconstruction of the structure of uncycled/cycled cathode particles obtained from X-ray and electron microscopy.
