Well-defined Na2Zn3[Fe(CN)(6)](2) nanocrystals (similar to 300 nm) have been fabricated by a facile controlled crystallization method from low-cost precursors at room temperature. By employing [Fe(CN)(6)](3-)/[Fe(CN)(6)](4- )couples as redox centres, this material can realize a theoretical 1Na-storage capacity of 70 mAh g(-1), a superior high-rate capability of 20 C and an impressive cycle life of 1000 cycles, offering a low-cost and high-performance alternative cathode for large-scale Na-ion applications.
