Structure optimization of Prussian blue analogue cathode materials for advanced sodium ion batteries.

چکیده
A structure optimized Prussian blue analogue Na1.76Ni0.12Mn0.88[Fe(CN)6]0.98 (PBMN) is synthesized and investigated. Coexistence of inactive Ni(2+) (Fe-C≡N-Ni group) with active Mn(2+/3+) (Fe-C≡N-Mn group) balances the structural disturbances caused by the redox reactions. This cathode material exhibits particularly excellent cycle life with high capacity (118.2 mA h g(-1)).

Mesocrystalline coordination polymer as a promising cathode for sodium-ion batteries.
Prussian blue (PB) mesocrystals with Na as the alkaline metal were synthesized and used as cathode materials in Na-ion batteries. The mesocrystalline structure endowed PB with very different phase change behavior and electrochemical performance in contrast to PB single-crystals in cyclic voltammograms and galvanostatic discharge/charge voltage profiles of PB/Na half-cells.

Copper hexacyanoferrate (CuHCF) nanoparticles with tunnel-like Prussian blue structure were deposited on graphite substrate via pulse galvanostatic electrochemical deposition at 25 mA cm-2 with both on-time and off-time periods of 0.1 s, which presented the ability to intercalation/de-intercalation of Al ions reversibly in aqueous solution. The crystal structure of the as-prepared CuHCF f...
متن کاملPrussian blue: a new framework of electrode materials for sodium batteries.
Prussian blue and its analogues consisting of different transition-metal ions (Fe, Mn, Ni, Cu, Co and Zn) have been synthesized at room temperature. Insertion of Na into KFe(2)(CN)(6) in a carbonate electrolyte exhibited a reversible capacity near 100 mA h g(-1) with no capacity fade in 30 cycles. The data indicate that a Na-ion battery with a Prussian blue framework as a cathode will be feasible.
متن کاملPrussian Blue Analogue Mesoframes for Enhanced Aqueous Sodium-ion Storage
Mesostructure engineering is a potential avenue towards the property control of coordination polymers in addition to the traditional structure design on an atomic/molecular scale. Mesoframes, as a class of mesostructures, have short diffusion pathways for guest species and thus can be an ideal platform for fast storage of guest ions. We report a synthesis of Prussian Blue analogue mesoframes by...
متن کاملSodium zinc hexacyanoferrate with a well-defined open framework as a positive electrode for sodium ion batteries.
A modified Prussian blue analogue, Na(2)Zn(3)[Fe(CN)(6)](2)·xH(2)O, was investigated as a positive electrode material. Utilizing a well-defined channel structure, the compound exhibits a clear electrochemical activity at around 3.5 V vs. Na/Na(+) with a reversible capacity of 56.4 mA h g(-1) and good cycle life.
