“…41 Also, Co 3+ doping prevents the cationic disorder in LiNi 0.94 Co 0.06 O 2 with good thermal and structural stability and improved electrochemical performance for Li-ion, Na-ion, and supercapacitor applications. 42 Lithium and sodium-based hybrid layered oxide Na 2/3 Li 1/3 Mn 0.95 Co 0.05 O 2 with 5% Co concentration at the Mn site showed a reversible capacity of 112 mAh/g with a capacity retention of 97.7% after 100 charge−discharge cycles at 0.1 C. 43 There are also many reports on the development of low cobalt active materials due to their high specific capacity and energy density, as summarized in the literature. 44 It has been reported that the Co substitution exhibits excellent chemical stability, structural stability, and dissolution stability in layered oxides owing to the large octahedral site and stabilization energy as compared to Ni/Mn doping.…”

In recent years, the Na-ion SuperIonic CONductor (NASICON) based polyanionics are considered pertinent cathode materials in sodium-ion batteries due to their 3D open framework, which can accommodate a wide range of Na content and can offer high ionic conductivity with great structural stability. However, owing to the inferior electronic conductivity, these materials suffer from unappealing rate capability and cyclic stability for practical applications. Therefore, in this work we investigate the effect of Co substitution at the V site on the electrochemical performance and diffusion kinetics of Na3V2–x Co x (PO4)3/C (x = 0–0.15) cathodes. All the samples are characterized through Rietveld refinement of the X-ray diffraction patterns, Raman spectroscopy, transmission electron microscopy, etc. We demonstrate improved electrochemical performance for the x = 0.05 electrode with a reversible capacity of 105 mAh g–1 at 0.1 C. Interestingly, the specific capacity of 80 mAh g–1 is achieved at 10 C with retention of about 92% after 500 cycles and 79.5% after 1500 cycles and having nearly 100% Coulombic efficiency. The extracted diffusion coefficient values through the galvanostatic intermittent titration technique and cyclic voltammetry are found to be in the range of 10–9 to 10–11 cm2 s–1. The post-mortem studies show excellent structural and morphological stability after testing for 500 cycles at 10 C. Our study reveals the role of optimal dopant of Co3+ ions at the V site in improving the cyclic stability at a high current rate.

“…It is well established that cobalt plays an important role in enhancing the rate capability and the structural stability of layered oxides [34]. Nguyen's group reported that Co-doped Na 2/3 Li 1/3 Mn 0.95 Co 0.05 O 2 delivers the reversible capacity of 112 mAh g −1 at 0.1 C with retention of 97.7% after 100 cycles [35]. However, it is acknowledged that cobalt doping contributes to the rate capability and the cycle at the expense of some reversible capacity [36].…”

O3-type layered oxides are widely investigated as cathodes for Na-ion batteries (SIBs) due to their high theoretical capacities and splendid initial Coulombic efficiency. However, they suffer from fast capacity fading owing to the complicated phase transformations, especially in high cut-off voltage (>4 V). Herein, Ti and Co elements were simultaneously introduced to O3-Na(Ni0.3Fe0.2Mn0.5)0.85Ti0.1Co0.05O2 (NFMTC) cathode material, and the effects of Ti/Co co-doping on phase structure and electrochemical properties were analyzed in detail. The results reveal that Ti/Co co-doping can enhance the {010} plane, interlayer space and Na-ion diffusion kinetics, resulting in the improved electrochemical performance. Therefore, the NFMTC cathode delivers a high reversible capacity of 174.7 mAh g−1 at 0.1 C in the voltage range of 2.0–4.3 V and a good rate capability (53% of the initial capacity at 5 C) as well as an excellent capacity retention of 78% after 300 cycles at 1 C. This work maybe provides a guidance to explore high-performance cathode materials for sodium ion batteries.
