Fig. 2: CPD images of the cathode composite region obtained during CV operation.
From: Dynamically visualizing battery reactions by operando Kelvin probe force microscopy

The image size is 10 \(\mu\)m \(\times\) 4 \(\mu\)m. a–l Images obtained during the forward voltage sweep. m–x Images obtained during the backward sweep. LCP and Pd particles are enclosed by yellow and light blue dashed lines in (a), respectively. The remaining parts correspond to the LATP region. Cell voltages at the end of CPD imaging are displayed in the upper right corner of each image.
