Fig. 5: Electron density as a proxy for the SoC.

a The 3D rendering of an electrode with a monolayer of NMC 811 particles. b–d illustrates our correlative approach for imaging the same NMC particle. c The phase contrast image collected at ID16A, ESRF, Grenoble, France. d The spectroscopic imaging data of the same particle collected at 6-2C, SSRL, Menlo Park, CA, USA. e shows the changes of lattice unit cell volume, number of electrons per lattice unit cell, voltage (1 C), and electron density as a function of the SoC. The scale bars in (a) and (b) are 25 and 5 μm, respectively.
