A ternary prussian blue analogue (V1.07Cu0.35)Fe‐PBA and its annealed derivatives were prepared and investigated for their electrochemical behavior as lithium cathode material. The results indicate that the annealed one prepared at 200 °C under argon protection, though retains similar framework with the as‐prepared one, shows improved capacity (93 mA · h · g –1 at 50 mA · g –1 ), cycle stability (retaining 86 % of the capacity after 50 cycles) and rate capability, attributable to improved intercalation of Li ions via removing tunnel water from framework.
