Porous NaTi₂(PO₄)₃ Nanocubes Anchored on Porous Carbon Nanosheets for High Performance Sodium-Ion Batteries.

ABSTRACT: 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
