construction of N-doped TiCTconfined worm-like FeOnanoparticles by Fe-O-Ti bonding for LIBs anode with superior cycle performance.

The development of FeOas lithium-ion batteries (LIBs) anode is greatly restricted by its poor electronic conductivity and structural stability. To solve these issues, this work presentsconstruction of three-dimensional crumpled FeO@N-TiCTcomposite by solvothermal-freeze-drying process, in which wormlike FeOnanoparticles (10-50 nm)nucleated and grew on the surface of N-doped TiCTnanosheets with Fe-O-Ti bonding. As a conductive matrix, N-doping endows TiCTwith more active sites and higher electron transfer efficiency.
