Abstract：

Prussian　blue　analogues　as　cathode　material　for　sodium-ion　batteries　suffer　from　poor　cycling　stability　and　inferior　rate　performance　because　of　crystal　defects　and　sluggish　ion　diffusion　kinetics.　The　Na1.02Fe[Fe(CN)6]0.95·□0.05　Prussian　blue　nanoparticles　with　few　lattice　vacancies　and　a　yolk-shell　structure　are　designed　and　synthesized　to　address　these　two　problems.　The　hierarchical　structure　endows　yolk-shelled　Prussian　blue　nanoparticles　with　large　specific　surface　area,　large　pore　volume　and　short　ion　pathways.　As　a　result,　the　yolk-shell　Prussian　blue　nanoparticles　exhibit　a　high　discharge　capacity　(140　mA　h　g−1　at　0.1C),　high-rate　performance　(51　mA　h　g−1　at　10C)　and　excellent　cycling　stability　(95.8%　capacity　retention　after　500　cycles　at　1C).　©　2019　Elsevier　B.V.
