a Rate performance of Li | |Li symmetric cells at different current densities. b, c Voltage profiles of Li | |Li half cells at different current densities for HCE b and IHCE c. d The Li+ transference number of the SCE, HCE and IHCE. e Tafel plots for Li plating/stripping in SCE, HCE and IHCE. The inset shows the values of the corresponding exchange current densities. f Activation energies derived from Nyquist plots of cycled Li | |Cu cells with SCE, HCE and IHCE, respectively.
