Development, synthesis and optimization of a high-capacity anode based on the hexacyanometalate family for sodium water batteries, which can be used in ultra-fast and energy-intensive energy storage devices.
Results achieved:
the possibility of using silver hexacyanoferrate as an anode material Ag4[Fe(CN)6] for sodium-ion batteries is shown;
it was determined that the reversible reaction refers to the conversion reaction of the transformation of Ag4[Fe(CN)6];
a method for stabilizing the material during electrochemical cycling has been proposed, which consists of adding an iron salt (FeCl3), the ions of which bind the dissolving hexacyanoferrate and leave it on the surface of the electrode;
the test material is highly stable during long-term cycling; the material has an average capacity of 58 mAh/g over 500 charge/discharge cycles at a current of 200 mAh/g.
