(a) 3D volume rendering of the internal structure of the NMC811 cathode inside the lithium battery from the XCT data, showing a porous internal structure. (b) Overall energy spectrum obtained by XCS imaging in the top region (furthest from the separator) of the cathode at the fully charged state. (c) Corresponding Compton profile obtained from the Compton peak in (b). (d) EMF mapping across the xy plane in the top region of the cathode at the fully charged state from the XCS imaging data. |
