Glucose-Treated Manganese Hexacyanoferrate for Sodium-Ion Secondary Battery
Manganese hexacyanoferrate (Mn-PBA) is a promising cathode material for sodium-ion secondary battery (SIB) with high average voltage (=3.4 V) against Na. Here, we find that the thermal decomposition of glucose modifies the surface state of Mn-PBA, without affecting the bulk crystal structure. The glucose treatment significantly improves the rate properties of Mn-PBA in SIB. The critical dischar...

Morphology-Dependent Electrochemical Performance of Zinc Hexacyanoferrate Cathode for Zinc-Ion Battery
Zinc hexacyanoferrate (ZnHCF) which is a dimorphic (cubic or rhombohedral) Prussian blue analogue and can be intercalated by both monovalent and divalent ions,is a promising cathode material for rechargeable aqueous metal-ion batteries.In this paper, a simple co-precipitation method is developed to tune the particle morphology of ZnHCF by adjusting the dropping speed at room temperature. Three ...
متن کاملUniform manganese hexacyanoferrate hydrate nanocubes featuring superior performance for low-cost supercapacitors and nonenzymatic electrochemical sensors.
Uniform manganese hexacyanoferrate hydrate nanocubes are prepared via a simple chemical precipitation method at room temperature. Due to both micro/mesopores of the Prussian blue analogue and nanocubic structures, the manganese hexacyanoferrate hydrate nanocubes allow the efficient charge transfer and mass transport for electrolyte solution and chemical species. Thus, the manganese hexacyanofer...
متن کاملLow Voltage Charge/Discharge Behavior of Manganese Hexacyanoferrate
Recently, Prussian blue analogues (PBAs) have been reported to exhibit a low voltage charge/discharge behavior with high capacity (300–545 mAh/g) in lithium-ion secondary batteries (LIBs). To clarify the mechanism of low voltage behavior, we performed ex situ synchrotron radiation X-ray diffraction (XRD) and ex situ X-ray absorption spectroscopy (XAS) of a film of Na1.34Mn[Fe(CN)6]0.84·3.4H2O w...
