“…These results indicate that the mechanism of sodium storage is alloying. Combining the results of XRD and XPS with the previous reports, [ 29,30 ] we can draw a conclusion that the process of sodium storage of NiSb@PEO electrodes is as follows. Sodiation: NiSb + 3Na + + 3e − → Na 3 Sb + Ni; Desodiation: Na 3 Sb → Sb + 3Na + + 3e − .…”

Antimony has a high theoretical capacity, is widely used as an anode material for sodium‐ion batteries (SIB). However, the reversible sodiation/desodiation causes the structure collapse of the materials and then a rapid capacity fade. To solve this issue, the rationally designed NiSb@PEO (PEO, polyethylene oxide) hierarchical hollow nanospheres are successfully synthesized via the combination of hydrothermal and galvanic replacement methods. The unique hierarchical hollow nanospheres can alleviate volume expansion and mechanical stress, maintaining structural integrity during cycling. The PEO coating offers a highly conducive network and is conducive to forming stable solid electrolyte interface film on the surface of NiSb nanospheres. In addition, the nanospheres can shorten the transport pathway for the charged species. Benefiting from these structural advantages, NiSb@PEO hollow nanospheres as anodes for SIB display excellent sodium storage properties. At the current density of 100 mA g−1, the initial charge specific capacity of the NiSb@PEO anode is 446 mAh g−1, and the capacity retains 82.5% after 100 cycles. NiSb@PEO can maintain a reversible capacity of 284 mAh g−1 even at a high current density of 1600 mA g−1.

“…Another peak at 852.2 eV could also be detected. Thus, they could be attributed to the element Ni in the Ni–Co alloy . In the charge state, the 2p 3/2 peaks at 855.7 and 853.0 eV are attributed to the Ni 3+ and Ni 2+ , respectively, in NiS x . , In the high-resolution XPS spectrum of Co in Figure b, in the pristine state, the peaks at 780.8 and 796.4 eV and at 779.3 and 794.6 eV should be denoted as Co 3+ and Co 2+ , respectively .…”

Bimetal Synergistic Effect Induced High Reversibility of Conversion-Type Ni@NiCo₂S₄ as a Free-Standing Anode for Sodium Ion Batteries

Conversion-type anode materials for sodium ion batteries have received extensive attention because of their relatively high theoretical capacity. However, multiple challenging obstacles stand in the way of their commercial application, especially their poor cycling stability resulting from the bad reversibility of the conversion reaction. Herein, Ni–Co bimetal sulfide was selected and investigated with the goal of improving the reversibility of the conversion reaction owing to the similarity of Ni and Co. As expected, when three-dimensional hierarchical Ni@NiCo2S4 (NiCo2S4 nanowires growing on the Ni foam) was applied as the free-standing anode for sodium ion batteries, it demonstrated high capacity and excellent cycling stability (90.65%, 100 cycles) compared with those of monometallic sulfides. Various characterization [in situ X-ray diffraction (XRD), ex situ XRD, ex situ X-ray photoelectron spectroscopy, FESEM mapping, and high-resolution transmission electron microscopy] tests confirmed that the Ni–Co alloy was formed during the discharge process and effectively prevented the crystalline grain growth of conversion reaction products, improving the reaction kinetics and reversibility.

A cost-effective, facile solution-based hot-injection synthetic route has been developed to synthesize NiSb nanoparticles in oleylamine (OAm) using commercially available inexpensive precursor with reducing toxicity at a relatively low temperature of 160 • C. Especially, an organic reductant of borane-tert-butylamine complex is intentionally involved in the reaction system to promote a fast reduction of metallic Ni and Sb for the formation of the NiSb nanoparticles. Structural characterizations reveal that the NiSb nanoparticles are hexagonal phase with space group P6 3 /mmc and they are composed of small granules with size about 10 nm that tend to form agglomerates with porous-like geometries. This is the first report on the generation of transition metal antimonide via solution-based strategy, and the asfabricated nanoparticles possess actively electrocatalytic hydrogen evolution reaction (HER) property in acidic electrolytes when the long-chain ligand of OAm adhered on the surface of the nanoparticles is exchanged by ligand-removal and exchange procedure. It is found that the NiSb nanoparticles as a new kind of non-noble-metal HER electrocatalysts only require overpotentials of 437 and 531 mV to achieve high current densities of 10 and 50 mA/cm 2 respectively, as well as exhibit low charge transfer resistance and excellent HER stability.
