Dear XY

Thank you for your question. It sounds like you're looking for open source SEM images of porous electrodes of Li-ion batteries such as NMC, LFP, and LCO. I suggest searching for FIM/SEM imaging research papers online, such as on databases like PubMed, that may contain the images you need. Additionally, many scientific journals provide free access to some of their content to help promote research. You might also search academic forums and websites, such as Stack Exchange, to connect with people who have done similar research and can provide more details or images. Good luck in your search!

Zhang et al. (2015) and Rashid and Gupta (2017) have published SEM images representing the electrode microstructure of an NMC cathode, graphite (MCMB) anode, and LMO cathode. You can also find surface SEM images of nonporous and porous Si alloy anodes.

Thank you Dr. R. Sagayaraj and Dr. Giuseppe Di Palma for your detailed answer. I may make it unclear in the originial Question, I want to find open source 3D FIB/SEM images of porous electrodes. So, I have started a new question here https://www.researchgate.net/post/Open_source_3D_FIB_SEM_data_of_porous_electrode_of_Li-ion_batteries

Any input will be greatly appreciated. Thank you for your kind help.
