Sodium Ion Battery Cathode Material Prussian Blue Na2fefe(cn)6*2H2O
Prussian blue frame structure allows sodium ions to be embedded and released quickly, with excellent structural stability and rate performance. Prussian blue cathode material is a potential sodium ion storage material because of its simple preparation process and stable structure. Performance of Fennac in half-cell configuration in a Swagelok cell using 1.5 M NaPF6 in DME as electrolyte. The cell was cycled at 0.05C between 4 and 2 volts vs. Na+/Na.
Performance of a Fennac cathode in full-cell configuration vs. Hard-carbon at 0.2C current. The cell used 1 M NaPF6 in EC:DEC 1:1 as the electrolyte.
