Abstract
Anionic intercalation into graphite is strongly temperature-dependent. At 333 K, it stops being a sequential process for PF6− and FSI− species, mainly proposed for dual-ion batteries, whereas for ClO4−, no mechanism change is visible from operando XRD. These phenomena might represent one of the critical limitations for dual-graphite systems.
