Porous TiN nanoparticles embedded in a N-doped carbon composite derived from metal–organic frameworks as a superior anode in lithium-ion batteries†
Abstract
A porous TiN/N-doped carbon composite electrode prepared via a metal–organic framework strategy exhibited high reversible lithium specific capacity (561 mA h g−1 at 50 mA g−1), excellent rate capability (281 mA h g−1 at 2 A g−1), and good cycle stability (310 mA h g−1 at 2 A g−1 for 400 cycles).
