Large anions exhibit slow diffusion kinetics in graphite cathode of dual-ion batteries (DIBs); particularly at high current density, it suffers severely from the largely-reduced interlayer utilization of graphite cathode, which as a bottleneck limits the fast charge application of DIBs. To maximize interlayer utilization and achieve faster anion diffusion kinetics, a fast and uncrowded anion transport channel must be established. Herein, Li⁺ was pre-intercalated into the graphite paper (GP) cathode to increase the interlayer spacing, and then hosted for the ${\mathrm{P}\mathrm{F}}_6^{-}$ anion storage. Combined with theoretical calculation, it shows that the local interlayer spacing enlargement and the residual Li⁺ reduce the anion intercalation energy and diffusion barrier, leading to better rate stability. The obtained GP with Li⁺ pre-intercalation (GP-Li) electrode exhibits a discharge capacity of 23.1 mAh g⁻¹ at a high current of 1300 mA g⁻¹. This work provides a facile method to efficiently improve the interlayer utilization of graphite cathode at large currents.
