“…10 A weak peak at 447 cm À1 could have arisen from the symmetric stretching of Sb-S-S-Sb. 23 In the high frequency region from 1200 to 1600 cm À1 (Fig. 1e), two peaks at 1332 and 1590 cm À1 were attributed to the D-band, which were characteristic peaks of the C sp 2 hybrid orbital because of the G-band, a disorder arrangement of the carbon atom, or lattice defects, suggesting an ordered lattice structure from the vibration of C sp 2 in the plane.…”

Advances and Challenges in Metal Sulfides/Selenides for Next‐Generation Rechargeable Sodium‐Ion Batteries

Rechargeable sodium-ion batteries (SIBs), as the most promising alternative to commercial lithium-ion batteries, have received tremendous attention during the last decade. Among all the anode materials for SIBs, metal sulfides/selenides (MXs) have shown inspiring results because of their versatile material species and high theoretical capacity. They suffer from large volume expansion, however, which leads to bad cycling performance. Thus, methods such as carbon modification, nanosize design, electrolyte optimization, and cut-off voltage control are used to obtain enhanced performance. Here, recent progress on MXs is summarized in terms of arranging the crystal structure, synthesis methods, electrochemical performance, mechanisms, and kinetics. Challenges are presented and effective ways to solve the problems are proposed, and a perspective for future material design is also given. It is hoped that light is shed on the development of MXs to help finally find applications for next-generation rechargeable batteries.

“…Thus, to obtain better electrochemical properties, the contents of conduction materials should be increased. It has been found that the embedding of anode materials in carbon/graphene matrixes can realize high content of conductive carbon materials for enhanced electrochemical properties (Fu et al, 2015; Guo et al, 2015; Choi et al, 2016; Sun et al, 2016). Motivated by the above potentials, we have prepared porous NaTi 2 (PO 4 ) 3 nanocubes anchored on porous carbon nanosheets (NaTi 2 (PO 4 ) 3 /C) through ultrasonic treatment.…”

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

et al. 2018

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.
