Fe 3 N constrained inside C nanocages as an anode for Li-ion batteries through post-synthesis nitridation

Carbon-constraint Fe3N nanoparticles (Fe3[email protected]) with a unique core-shell structure are successfully realized through a facile 2-step process: fabricating [email protected] core-shell nanoparticles by DC arc-discharge method and subsequently converting them into Fe3[email protected] through chemical nitriding reactions. A series of technological conditions are carried out to manipulate the core components and the shell structure....
