Cube-shaped porous carbon (CPC) was obtained from the carbonization of MOF-5 (Zn4O(OOCC6H4COO)(3)) crystals and shows abundant micro/mesopores, high mechanical strength, largest surface area (2316 m(2) g(-1), BET method) and good electrical conductivity (a high weight ratio 98.17/1.83 of C/O). When utilized as anode material for sodium-ion batteries, the CPC presents a high overall sodium storage capacity similar to 240 mAh g(-1) at a current density of 100 mA g(-1) after 100 cycles, and maintains a high specific capacity of 100 mAh g(-1) after 5000 cycles at a current density of 3200 mA g(-1). For the advantages of this unique carbon framework structure, the CPC might be a promising anode material for the application of SIBs. (C) 2016 Elsevier Ltd. All rights reserved.
