Fig. 6: Schematic procedures and relative energy diagrams for each state describing thermal impact on charged graphite/SiO composite anode.

From: SiO-induced thermal instability and interplay between graphite and SiO in graphite/SiO composite anode

Fig. 6

a Pristine state, fully wetted anode comprised of graphite (gray), SiO (green), and conductive agent (black). b Step 1, fully lithiated graphite (yellow) and SiO (light gray) after charging. c Step 2, partially de-lithiated SiO with transformed SEI after exposed to the elevated temperature. d Step 3, electron movement from graphite to SiO and concomitant lithium-ion de-intercalation from the graphite (orange). e Step 4, lithium exhaustion in the graphite (gray) upon prolonged thermal aging.
