Electrodeposition of Ni5Sb2 nanowires array and its application as a high-performance anode material for lithium ion batteries

Copper Antimonide Nanowire Array Lithium Ion Anodes Stabilized by Electrolyte Additives

“…Herein, we present nanowire arrays of a CuSb alloy produced by electrodeposition within the pores of nanoporous alumina oxide templates. Although this method has been used to produce nanowire array electrodes from similar materials such as Cu 2 Sb, CoSb, Ni 5 Sb 2 , and Cu/Cu 2 O, the antimony-based nanowires typically show short cycle lives of only 5–50 cycles. We show that the limited performance of this material comes primarily from unstable surface chemistry that causes the formation of a thick layer of solid electrolyte interface (SEI) material that is constituted by organic and inorganic decomposition products from the electrolyte.…”

Low-temperature physical properties and electronic structures of Ni 3 Sb, Ni 5 Sb 2 , NiSb 2 , and NiSb

“…[23] Bulk NiSb and nanosized Ni 5 Sb 2 , NiSb, and NiSb 2 have been studied as promising electrode materials in lithium-ion batteries recently. [24][25][26][27] To the best of our knowledge, only the lowtemperature resistivity and susceptibility of NiSb were studied previously. NiSb was found to be a typical Pauli paramagnetic metal by resistivity and susceptibility measurements.…”

Realizing Efficient Catalytic Performance and High Selectivity for Oxygen Reduction Reaction on a 2D Ni2SbTe2 Monolayer

“…Moreover, to show the chemical stability, we performed the AIMD simulation for the Ni 2 SbTe 2 monolayer, which is exposed in an O 2 environment at 300 K. We found that no spontaneous reconstruction could be observed after 10 ps, indicating that the Ni 2 SbTe 2 monolayer is stable and encouraged for the application under ambient conditions (Figure S3). Besides, some nanostructures, such as nickel antimonide (NiSb) and nickel telluride (NiTe and NiTe 2 ), all of which can be regarded as the components of the Ni 2 SbTe 2 monolayer, have high stability and can be experimentally used as electrocatalysts in acidic medium . Overall, the Ni 2 SbTe 2 monolayer can be highly expected to be stable during the electrocatalytic ORR process.…”
