“…In addition, the Na layer (O-Na-O) thickness of NFMTC and NFMT are 3.319 Å and 3.312 Å, respectively, which are larger than that of that of NFM (3.299 Å). It is well established that the increased Na layer thickness would accelerate the Na-ion diffusion, and improve the electrochemical performance of layered oxide cathode [38]. Meanwhile, the transition-metal layers (TM) expand from 2.138 Å for NFM to 2.146 Å for NFMT and 2.151 Å for NFMTC.…”

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.

“…[ 146–148 ] For example, it was proposed that Al doping can shorten the bond length of TM–O and expand the interlayer spacing of the Na layer by increasing the TM–O bond energy, thereby improving the cycling reversibility and ionic diffusion kinetics of the resulting cathode (NaAl 0.02 Ni 0.49 Mn 0.49 O 2 ). [ 142 ] The modified NaNi 0.5 Mn 0.5 O 2 cathodes doped with Zr, [ 149 ] Ti, [ 150 ] tin (Sn), [ 151 ] and Sb [ 152 ] also demonstrated similar results. A novel O3–Na 0.78 Li 0.18 Ni 0.25 Mn 0.583 O w cathode material was synthesized by electrochemical Na/Li‐ion exchange, which provided an ultra‐high reversible capacity of 240 mA h g −1 and a total energy density of 675 W h g −1 within a voltage window of 1.5–4.5 V. [ 153 ] In addition, the introduction of non‐toxic Ca 2+ into the Na‐layer has been proposed.…”

In recent decades, sodium‐ion batteries (SIBs) have received increasing attention because they offer cost and safety advantages and avoid the challenges related to limited lithium/cobalt/nickel resources and environmental pollution. Because the sodium storage performance and production cost of SIBs are dominated by the cathode performance, developing cathode materials with large‐scale production capacity is the key to achieving commercial applications of SIBs. Therefore, developing host materials with high energy density, long cycling life, low production cost, and high chemical/environmental stability is crucial for implementing advanced SIBs. Among the developed cathode materials for SIBs, O3‐type sodiated transition‐metal oxides have attracted extensive attention owing to their simple synthesis methods, high theoretical specific capacity, and sufficient Na content. However, the relatively large Na‐ion radius leads to sluggish diffusion kinetics and inevitable complex phase transitions during the deintercalation/intercalation process, resulting in poor rate capability and cycling stability. Therefore, this review comprehensively summarizes the research progress and modification strategies for O3‐type cathodes, including the component design, surface modification, and optimization of synthesis methods. This work aims to guide the development of commercial layered oxides and provide technical support for the next generation of energy‐storage systems.

With the Keggin structure PMo 12 O 40 3− of phosphomolybdic acid (PMA) taken into account, the interfacial physicochemical property of PMA was adjusted through Li-ion exchange, and then Liexchanged PMA was adopted to modify the cathode material LiNi 0.9 Mn 0.1 O 2 (NM91) via the solid-phase method, aiming at improving the rate performance and cycling stability of the cathode. The optimal ion-exchanged PMA (PMA-e2)-modified NM91 (named 91PMA-e2) shows an initial discharge capacity of 216.6 mAh g −1 at 0.1 C and a capacity retention of 84.8% after 100 cycles (1 C and 2.8−4.5 V) as well as the best rate performance, which is superior to those of pristine NM91. With characterization by X-ray diffraction (XRD), X-ray photoelectron spectroscopy, high-resolution transmission electron microscope, in situ XRD measurements, etc., it indicates that PMA-e2 modification can reduce the Li/Ni mixing degree but enlarge the thickness of the lithium layer (T LiOd 6 ) and facilitate Li + diffusion. The results suggest that the Keggin structure of PMA as well as the acidity property and priority adsorption toward water molecules are associated with the Li-ion exchange degree. In combination with the depth-profiling XPS measurement of the spent samples experienced in 300 cycles, it illustrates that spent 91PMA-e2 possesses higher amounts of LiF and Ni 3+ but a lower amount of Li x PO y F z , which are due to the coating layer generated from the Keggin structure of PMA-e2. Such a Keggin structure has the capacity to trap trace amounts of water and inhibit the hydrolysis reaction of PF 5 , consequently maintaining the stable structure of the cathode and achieving superior cycling retention.
