NaTi2(PO4)3因其开放的三维框架结构和充放电过程中有限的体积变化而作为钠离子电池负极材料引起了人们的极大兴趣。然而，NaTi2(PO4)3 较差的本征电子电导率需要改善才能获得高倍率性能。在这项工作中，设计和开发了锚定在多孔碳纳米片上的多孔NaTi2(PO4)3纳米立方体(NaTi2(PO4)3/C)。该材料表现出大的放电容量和良好的倍率容量，在0.1 A g-1的电流密度下首次放电容量为485 mAh g-1，即使在2000次循环后，在4 A g-1的高倍率下仍保留98 mAh g-1。这些结果表明NaTi2(PO4)3/C是一种有前途的钠离子电池负极材料。
NaTi2(PO4)3 has attracted great interest as anode material for sodium ion batteries owing to its open three-dimensional framework structure and limited volume changes during the charge and discharge process. However, the poor intrinsic electronic conductivity of NaTi2(PO4)3 needs to be improved for high rate capability. In this work, porous NaTi2(PO4)3 nanocubes anchored on porous carbon nanosheets (NaTi2(PO4)3/C) are designed and developed. This material exhibits a large discharge capacity and good rate capacity including a first discharge capacity of 485 mAh g−1 at a current density of 0.1 A g−1, and 98 mAh g−1 retained at a high rate of 4 A g−1 even after 2,000 cycles. These results suggest that NaTi2(PO4)3/C is a promising anode material for sodium-ion batteries.
