Extended Data Fig. 5: Behaviour of biphasic transitions upon (de)lithiation for five cycles at 2C.
From: Operando optical tracking of single-particle ion dynamics in batteries
a–j, Sequential differential images of the active particle upon delithiation (a, c, e, g, i) and lithiation (b, d, f, h, j) during the biphasic transition, for all five galvanostatic cycles at 2C (as plotted in Fig. 1b, c). The black dashed lines are a guide for the eye, representing the phase boundary position. Sequential contrast (colour scale) represents the intensity changes over a 20 s timescale, and the colour scale is consistent throughout all images. Scale bar, 5 μm.
