Ultrafine NaTi(2)(PO(4))(3) Nanoparticles Encapsulated in N-CNFs as Ultra-Stable Electrode for Sodium Storage

We present a feasible method for the preparation of one-dimensional N-doping carbon nanofibers encapsulated NaTi(2)(PO(4))(3) (NTP-NCNFs) through electrospinning accompanied by calcination. The poor electrical conductivity of NTP is significantly improved and the as-prepared NTP-NCNFs exhibit stable...

description We present a feasible method for the preparation of one-dimensional N-doping carbon nanofibers encapsulated NaTi(2)(PO(4))(3) (NTP-NCNFs) through electrospinning accompanied by calcination. The poor electrical conductivity of NTP is significantly improved and the as-prepared NTP-NCNFs exhibit stable and ultrafast sodium-storage capability. The NTP-NCNFs maintains a stable specific capacity of 121 mAh g(−1) at 10 C after 2,000 cycles, which only drop to 105 mAh g(−1) after 20,000 cycles. Furthermore, the NTP-NCNFs show excellent rate performance from 0.2 to 20 C, whose recovery efficiency still reaches 99.43%. The superior electrochemical property is mainly attributed to the large specific surface area, high porosity, N-doping carbon coating, and one-dimensional structure of NTP-NCNFs.
