In this work, the reduced graphene oxide/NaTi2(PO4)(3) (rGO/NTP) nanocomposite has been prepared by employing MXene as both the template and precursor for lithium ions battery with the enhanced performance. It is found that the NTP nanoparticles compact together and tightly decorate on the rGO layer. This novel structure benefits to shorten the diffusion path of Li+ and provide high conductivity, which are proved by the density functional calculations. Further, the Li+ diffusion coefficient of rGO/NTP is 3.68 x 10(-9) cm(2)center dot s(-1) which is much higher than that of the NTP (7.18 x 10(-10) cm(2)center dot s(-1)). The results demonstrate that the rGO/NTP anode offers the high specific discharge capacity of 400.9 mAh center dot g(-1) after 200 cycles at 0.1 A center dot g(-1), which is nearly twice higher than that of NTP anode. Even the current density varied from 0.1 to 2 A center dot g(-1), the specific capacity rGO/NTP anode can reach to 149.2 mAh center dot g(-1). Further, the integrity of the lamellar structure rGO/NTP anode remained after 200 cycles, highlighting the superior stability.
