Novel NiCo2S4 nanorods arrays are uniformly grown onto carbon nanofibers (NiCo2S4@CNF) through a facile hydrothermal approach. The elaborate designed composite structure ensures that the NiCo2S4 nanorods arrays are uniformly dispersed on the surfaces of carbon nanofibers (CNF) and tightly bonded with each other. The conductive networks of CNF can facilitate the electron transport at the interfaces and ions diffusion to readily react with NiCo2S4, thus leading to increased sodium storage. In view of this, NiCo2S4@CNF reveals a high reversible capacity (683.6 mAh g− 1 at 0.1 A g− 1) and long-term cycle stability (only attenuates 0.07% in each cycle after 400 times). This work provides a simple and efficient strategy for synthesizing high-performance sodium ion battery electrodes.

Conversion type ternary NiCo2S4, exhibiting high electrical conductivity (~1.25 × 106 S m-1) and high theoretical capacity (703 mAh g-1), has gained interest as an anode material for sodium-ion batteries (SIBs). Despite its potential, NiCo2S4 (NCS) has extensive volume expansion during cycling. This study introduces the NCS-multi-walled carbon nanotube (MWCNT) onto a carbon fiber (CF) electrode (NCS and NCS-MWCNT@CF), developed through electrodeposition, which addresses these limitations. The unique sheet-like morphology of NCS, featuring abundant pores, ensures good access to the electrolyte. Incorporating a three-dimensional conductive CF framework that acts as a free-standing current collector helps prevent the agglomeration of NCS particles and mitigates volume expansion by providing enough buffer space in the layers of the CF matrix. Our findings reveal that NCS on CF electrodes deliver a second cycle capacity of 620 mA g-1 at 30 mA g-1 and retain 72 % capacity after 200 cycles. At 200 mA g-1, the NCS@CF electrodes deliver 378 mAh g-1 in the second cycle with 68% capacity retention in the 200th cycle, whereas NCS-MWCNT@CF delivers 538 mAh g-1 at 200 mA g-1, maintaining 86 % capacity after 100 cycles, making it a potential anode for SIBs.

[26][27][28] ), mainly due to the poor electrical conductivity, agglomeration of intermediate products and severe volume expansion effect during cycling when the NiCo 2 S 4 intrinsic material is used as the anode for SIBs. In addition, metal doping is also a type of structural engineering, mainly by modulating the electronic structure and thus enhancing the electrical conductivity of the electrode material.…”

The development of high‐performance electrode materials is crucial for the advancement of sodium ion batteries (SIBs), and NiCo2S4 has been identified as a promising anode material due to its high theoretical capacity and abundant redox centers. However, its practical application in SIBs is hampered by issues such as severe volume variations and poor cycle stability. Herein, the Mn‐doped NiCo2S4@graphene nanosheets (GNs) composite electrodes with hollow nanocages were designed using a structure engineering method to relieve the volume expansion and improve the transport kinetics and conductivity of the NiCo2S4 electrode during cycling. Physical characterization and electrochemical tests, combined with density functional theory (DFT) calculations indicate that the resulting 3 % Mn‐NCS@GNs electrode demonstrates excellent electrochemical performance (352.9 mAh g−1 at 200 mA g−1 after 200 cycles, and 315.3 mAh g−1 at 5000 mA g−1). This work provides a promising strategy for enhancing the sodium storage performance of metal sulfide electrodes.
