We report the synthesis, structure, and electrochemistry of the first Na+-ion cathode with two distinct types of polyanions: Fe3P5SiO19. The Fe-based cathode has a reversible capacity of ca. 70 mAh g-1; ca. 1.7 Na+ ions per formula can be inserted/extracted at an average voltage of 2.5 V versus Na+/Na.
