The first Fe-based Na+-ion cathode with two distinct types of polyanions: Fe3P5SiO19

Herein, we report the synthesis, structure, and electrochemistry of the first Na + -ion cathode with two distinct types of polyanions: Fe 3 P 5 SiO 19 . The Fe-based cathode has a reversible capacity of ca. 70 mA h g −1 ; ca. 1.7 Na + ions per formula can be inserted/extracted at an average voltage...

Description
Summary:Herein, we report the synthesis, structure, and electrochemistry of the first Na + -ion cathode with two distinct types of polyanions: Fe 3 P 5 SiO 19 . The Fe-based cathode has a reversible capacity of ca. 70 mA h g −1 ; ca. 1.7 Na + ions per formula can be inserted/extracted at an average voltage of 2.5 V versus Na + /Na. Herein, we report the synthesis, structure, and electrochemistry of the first Na + -ion cathode with two distinct types of polyanions: Fe 3 P 5 SiO 19 .
