Charge/discharge curve of thin-film electrodes of (a) Li_0.68Na_0.04Ni[Fe(CN)₆]_0.68·5.1H₂O, (b) Li_0.71Na_0.13Co[Fe(CN)₆]_0.71·3.8H₂O, (c) Li_1.24Mn[Fe(CN)₆]_0.81·3.0H₂O, and (d) Li_0.96Na_0.88Cd[Fe(CN)₆]_0.96·4.8H₂O against Li at various rate (𝑣). The discharge curve at 𝑣 was measured after the charge process at 𝑣.
