Carbon-coated FeP nanoparticles anchored on carbon nanotube networks as an anode for long-life sodium-ion storage†
Abstract
A novel electrode design strategy of carbon-coated FeP particles anchored on a conducting carbon nanotube network (CNT@FeP-C) is designed to achieve superior sodium ion storage. Such a unique structure demonstrated excellent long-life cycling stability (a 95% capacity retention for more than 1200 cycles at 3 A g−1) and rate capability (delivered 272 mA h g−1 at 8 A g−1).
