“…To address these critical issues, a large amount of research is currently devoted to the co-assembly of TMCs with carbon materials into various composites, such as yolk–shell structured CoSe 2 /C nanospheres, 13 NiCo 2 Se 4 @NPC nanocubes, 14 and NiTe 2 /NC hexagonal nanosheets. 15 The morphology and structure of the composites has been optimized, which enhanced the sodium storage capability of the corresponding anodes. Notably, the coated carbon matrix improved the electrical conductivity of the composites on the one hand, and buffered the volume change of TMCs during the sodium-ion insertion/extraction process on the other hand.…”

Electrodes made of composites with heterogeneous structure hold great potential for boosting ionic and charge transfer and accelerating electrochemical reaction kinetics. Herein, hierarchical and porous double‐walled NiTeSe–NiSe2 nanotubes are synthesized by a hydrothermal process assisted in situ selenization. Impressively, the nanotubes have abundant pores and multiple active sites, which shorten the ion diffusion length, decrease Na+ diffusion barriers, and increase the capacitance contribution ratio of the material at a high rate. Consequently, the anode shows a satisfactory initial capacity (582.5 mA h g−1 at 0.5 A g−1), a high‐rate capability, and long cycling stability (1400 cycles, 398.6 mAh g−1 at 10 A g−1, 90.5% capacity retention). Moreover, the sodiation process of NiTeSe–NiSe2 double‐walled nanotubes and underlying mechanism of the enhanced performance are revealed by in situ and ex situ transmission electron microscopy and theoretical calculations.

Pseudocapacitance-boosted ultrafast and stable Na-storage in NiTe₂ coupled with N-doped carbon nanosheets for advanced sodium-ion half/full batteries

Abstract: Developing high-rate and durable anode materials for sodium-ion batteries (SIBs) is still a challenge because of the larger ion radius of sodium compared with the lithium ion during charge–discharge processes.
