“…The high electrochemical performance and long‐term stability of MNC‐2/NF electrode can be attributed to its high surface area, mesoporous nature, and high pore volume, which can enhance electrolyte diffusion and resultantly intercalation of Li + into active phases. Also, it can provide more empty spaces to accommodate volume change during the intercalation reaction 25,26 . The demonstrated electrochemical performance of MNC‐2/NF for LIB is superior and comparable with the earlier reported NiCo 2 O 4 based anode materials, summarized in Table S3 8,14,17‐19,23‐28 …”

Summary Rational design of ternary transition metal oxides for electrochemical energy storage and conversion application is highly desirable due to their synergetic effect and structural modifications. In this regards, binder‐free urchin‐like Mn substituted NiCo2O4 microspheres grown on conducting substrate by co‐precipitation method followed by calcination. Direct growth of active material on nickel foam (Mn0.1Ni0.9Co2O4/NF) results in a high reversible capacity of 1076 mAh/g at current density of 1.6 A/g and excellent stability of 350 cycles. As compared to bimetallic NiCo2O4, improved electrochemical performance of Mn substituted NiCo2O4 is mainly ascribed to the 3D structure with high surface area and abundant mesopores, which can efficiently reduce the diffusion length of ions and improve the structural stability by providing enough space for volume expansion during delithiation/lithiation processes.

“…Even ethanol as the solvent can also initiate the formation of metal carbonate hydroxides. Two-dimensional porous NiCo 2 O 4 nanodisks were synthesized by a low-temperature hydrothermal method by Jain et al [114] [99]. HMTA is hydrolyzed to produce NH 3 which finally produces OH − ions as stated earlier in this section (Eq.…”

Non-enzymatic biosensors based on mixed transition metal oxides are deemed as the most promising devices due to their high sensitivity, selectivity, wide concentration range, low detection limits, and excellent recyclability. Spinel NiCo2O4 mixed oxides have drawn considerable attention recently due to their outstanding advantages including large specific surface area, high permeability, short electron, and ion diffusion pathways. Because of the rapid development of non-enzyme biosensors, the current state of methods for synthesis of pure and composite/hybrid NiCo2O4 materials and their subsequent electrochemical biosensing applications are systematically and comprehensively reviewed herein. Comparative analysis reveals better electrochemical sensing of bioanalytes by one-dimensional and two-dimensional NiCo2O4 nano-/microstructures than other morphologies. Better biosensing efficiency of NiCo2O4 as compared to corresponding individual metal oxides, viz. NiO and Co3O4, is attributed to the close intrinsic-state redox couples of Ni3+/Ni2+ (0.58 V/0.49 V) and Co3+/Co2+ (0.53 V/0.51 V). Biosensing performance of NiCo2O4 is also significantly improved by making the composites of NiCo2O4 with conducting carbonaceous materials like graphene, reduced graphene oxide, carbon nanotubes (single and multi-walled), carbon nanofibers; conducting polymers like polypyrrole (PPy), polyaniline (PANI); metal oxides NiO, Co3O4, SnO2, MnO2; and metals like Au, Pd, etc. Various factors affecting the morphologies and biosensing parameters of the nano-/micro-structured NiCo2O4 are also highlighted. Finally, some drawbacks and future perspectives related to this promising field are outlined.

“…The characteristic diffraction peaks of NiCo 2 S 4 (JCPDS 20-0728) were observed in all the three samples. Moreover, the peaks in NiCo 2 S 4 /N-CNT were more pronounced and sharper than those in NiCo 2 S 4 /CNT [ 21 ]. It is believed that N-CNT can be used as active nucleation sites to promote the uniform and dense growth of NiCo 2 S 4 [ 22 ].…”

NiCo2S4 Nanocrystals on Nitrogen-Doped Carbon Nanotubes as High-Performance Anode for Lithium-Ion Batteries

et al. 2021

In recent years, the development of lithium-ion batteries (LIBs) with high energy density has become one of the important research directions to fulfill the needs of electric vehicles and smart grid technologies. Nowadays, traditional LIBs have reached their limits in terms of capacity, cycle life, and stability, necessitating their further improvement and development of alternative materials with remarkably enhanced properties. A nitrogen-containing carbon nanotube (N-CNT) host for bimetallic sulfide (NiCo2S4) is proposed in this study as an anode with attractive electrochemical performance for LIBs. The prepared NiCo2S4/N-CNT nanocomposite exhibited improved cycling stability, rate performance, and an excellent reversible capacity of 623.0 mAh g–1 after 100 cycles at 0.1 A g–1 and maintained a high capacity and cycling stability at 0.5 A g–1. The excellent electrochemical performance of the composite can be attributed to the unique porous structure, which can effectively enhance the diffusivity of Li ions while mitigating the volume expansion during the charge–discharge processes.
