“…In the HAADF STEM image, the measured distance between adjacent TM atoms is about 0.28 nm, which is consistent with the cell parameter a in the Rietveld refinement XRD results (Figure 1f) S4a). In the Co 2p spectrum of KMCAO, a double peak feature is observed at 780.1 eV and 795.2 eV, corresponding to Co 2p 3/2 and Co 2p 1/2 , respectively, indicating the trivalent state of Co ions in the sample (Figure 1i) [33]. The Al 2p spectrum of the KMCAO exhibits a characteristic peak at 73.3 eV, corresponding to Al 3+ (Figure 1j) [34].…”

Manganese-based layered oxides are promising cathode materials for potassium-ion batteries (PIBs) due to their low cost and high theoretical energy density. However, the Jahn-Teller effect of Mn3+ and sluggish diffusion kinetics lead to rapid electrode deterioration and a poor rate performance, greatly limiting their practical application. Here, we report a Co/Al co-substitution strategy to construct a P3-type K0.45Mn0.7Co0.2Al0.1O2 cathode material, where Co3+ and Al3+ ions occupy Mn3+ sites. This effectively suppresses the Jahn-Teller distortion and alleviates the severe phase transition during K+ intercalation/de-intercalation processes. In addition, the Co element contributes to K+ diffusion, while Al stabilizes the layer structure through strong Al-O bonds. As a result, the K0.45Mn0.7Co0.2Al0.1O2 cathode exhibits high capacities of 111 mAh g−1 and 81 mAh g−1 at 0.05 A g−1 and 1 A g−1, respectively. It also demonstrates a capacity retention of 71.6% after 500 cycles at 1 A g−1. Compared to the pristine K0.45MnO2, the K0.45Mn0.7Co0.2Al0.1O2 significantly alleviates severe phase transition, providing a more stable and effective pathway for K+ transport, as investigated by in situ X-ray diffraction. The synergistic effect of Co/Al co-substitution significantly enhances the structural stability and electrochemical performance, contributing to the development of new Mn-based cathode materials for PIBs.

Sodium-ion batteries (SIBs) are considered as an excellent alternative to lithium-ion batteries (LIBs) among various types of available batteries. Sodium-ion has the advantages of substantial natural abundance, low cost, and nearly similar physiochemical and electrochemical properties as lithium-ion. The cathode is vital in determining the cost and increasing the specific energy, cycling life, and overall performance of SIBs. The excellent electrochemical performance of a battery lies in the material science involved in its creation. For grid-scale energy storage at the commercial level, scale-up and engineering aspects are of at most importance. This review offers a brief overview of layered transition metal oxide (LTMO) synthesis via coprecipitation reaction, characterization techniques used for analysis, and hydrodynamic study as an effect of impeller type and scale-up aspects from a chemical engineering point of view for SIBs.

“…At present, the most studied sodium ion cathode materials mainly include transition metal layer oxides, polyanion compounds, prussian blue analogues, etc., because of their advantages and disadvantages, there is no clear dominant technical route. As the theoretical specific capacity of the existing cathode material is relatively low, it also becomes one of the main determinants of the overall capacity of the battery, and the cathode material occupies a large proportion in the secondary battery, so the performance of the cathode material often determines the performance of the battery and has an impact on the cost of the battery [76–78] . Figure 2 shows recent research results on cathode materials for SIBs [79] …”

Sodium‐ion batteries (SIBs) work similarly to lithium‐ion batteries, but they cost less and are safer. However, the battery has some shortcomings, such as low energy density and poor stability, which hinder its development and application. The development of electrode materials with low cost and high‐performance characteristics is a hot and difficult point in the research of SIBs. In this paper, the existing sodium ion cathode and anode materials are systematically reviewed. Firstly, the electrochemical structures and properties of various cathode and anode materials were introduced, and the limitations of cathode and anode materials of SIBs were analyzed. Based this, the current modification methods were summarized, such as surface coating of materials, doping of heteroatoms and metal elements to improve the electrochemical performance. In this paper, the research progress and modification measures of SIBs are summarized and prospected. It is helpful to further improve its comprehensive performance and lay a foundation for the future application of cathode and anode materials for SIBs.
