a Rate performance of the graphite electrode and the C2DP-G electrode. b Log (σ) as a function of T−1 for PP and C2DP-PP. c EPS plots of C2DP (isosurface value = 0.005 e Å−3). The blue and red colours denote deficient and rich electron density, respectively. d Simulated structure and e charge density difference plots (ρadsorbed − ∑ρisolated, isosurface value = 0.0002 e Å−3) of C2DP with PF6− as counter ions. f Schematic illustration of PF6−-diffusion paths and g the corresponding PF6−-diffusion energy barriers.
