Synthesizing the composite material of F-doped Fe₃N and an N-doped porous carbon framework will overcome the foregoing troubles and effectuate a preeminent electrochemical performance. In this study, we created a simple route to obtain the composite of F-doped Fe₃N nanoellipsoids and a 3D N-doped porous carbon framework under non-ammonia atmosphere conditions. Integrating the F-doped Fe₃N nanoellipsoids with an N-doped porous carbon framework can immensely repress the problem of volume expansion but also substantially elevate the lithium ion diffusion rate. When utilized as a negative electrode for lithium-ion batteries, this composite bespeaks a stellar operational life and rate capability, releasing a tempting capacity of 574 mAh g^-1 after 550 cycles at 1.0 A g^-1. The results of this study will profoundly promote the evolution and application of transition metal nitrides in batteries.Molecules (Basel, Switzerland)Facilely Fabricating F-Doped Fe₃N Nanoellipsoids Grown on 3D N-Doped Porous Carbon Framework as a Preeminent Negative Material.PMC109343142223004202522024PY0152022SYJXLX0782024QN0012020ZX013202310481005Liu XHuo ZZhang DYu CZhang CXu HShi XLiu GfalseFacilely Fabricating F-Doped Fe₃N Nanoellipsoids Grown on 3D N-Doped Porous Carbon Framework as a Preeminent Negative Material.Transition metal nitride negative electrode materials with a high capacity and electronic conduction are still troubled by the large volume change in the discharging procedure and the low lithium ion diffusion rate.
