Abstract:
In this paper, MOF-derived N-doped porous carbon anchoring Sn4P3 (Sn4P3@NPC) composite is prepared via a low-temperature phosphidation reaction with SnO2@NPC composite as the precursor. The as-prepared Sn4P3@NPC composite exhibit a high stable capacity of 319 mAh g(-1) at 0.1 A g(-1) after 100 cycles and improved rate performance (the capacities of 365, 322, 260, 204, and 146 mAh g(-1) at 0.1, 0.2, 0.5, 1, and 2 A g(-1), respectively) for sodium ion batteries. The good electrochemical sodium storage performance of the Sn4P3@NPC composite anodes can be ascribed to the synergistic effect between porous N-doped carbon and high-active Sn4P3 nanoparticles.
