Cation Configuration and Structural Degradation of Layered Transition Metal Oxides in Sodium-Ion Batteries

“…For example, Liu et al 11 focused on the application of LTMOs in commercial SIBs, and some macroscopic problems related to the interface issues, air sensitivity, and the applicable temperature of SIBs were elaborated in detail. Yang et al 12 supposed that the irreversible phase transitions, the Jahn−Teller effect, and the interface reactions are the main causes for the poor cycle performance of LTMOs in SIBs, while they ignored the deterioration effect of lattice oxygen reactions on the crystal effect at high voltages. Jia and co-workers 13 reviewed the influence of the orbital hybridization on the air stability, high voltage, and anion redox chemistry of LTMOs, which are helpful to the design and preparation of high-performance cathode materials.…”

“…Lithium-ion batteries (LIBs), as one of the earliest commercialized ESSs, have already changed our life by their applications in electric vehicles and mobile electronics. − However, due to the shortage of lithium resources and the rising price of lithium salts, sodium-ion batteries (SIBs) present broad market prospects as the alternatives to complement LIBs in sustainable energy storage devices. − Besides, the physicochemical affinities between lithium and sodium afford the development of SIBs by drawing upon the extensive and successful research foundations established for LIBs. Given the cathode material’s significant influence on a battery’s cost and its electrochemical attributessuch as cycle stability, rate capability, and energy densitythe exploration of suitable cathode materials for SIBs becomes paramount. − The investigation of cathode materials for SIBs mainly includes primarily transition metal oxides, − polyanion compounds, , and Prussian blue analogues. , Statistics over the past five years reveal a consistent annual growth in papers related to these cathode materials as shown in Figure a, and the volume of articles on layered transition metal oxide (LTMO) cathode materials surpasses that of the other two cathode materials. Moreover, a comprehensive comparison among these three types of cathode materials, as presented in Figure b, shows that despite the longevity and economic advantages offered by polyanion compounds and Prussian blue analogues, respectively, LTMOs demonstrate superior overall performance attributes.…”

Structural Engineering of Prussian Blue Analogues Enabling All-Climate and Ultralong Cycling Sodium-Ion Batteries

“…The integration of intermittent renewables (e.g., wave energy, solar, and wind) into the grid needs to be inclusive of emerging low-cost large-scale energy storage technologies. − For an evolving clean energy target with growing intermittent renewables, sodium-based rechargeable batteries are widely recognized as promising alternative energy storage systems to pumped hydro and compressed air due to the more cost-effective technology of battery manufacturing, the wide availability of sodium resources, and the simple infrastructure that is required. , Attempting to effectively operate under the significant fluctuation of temperature with day and night in the places where installation occurs, all-climate-applicable sodium-ion batteries (SIBs) have attracted great interest and are expected to be utilized for grid stations . Compared to the typical cathode materials for SIBs, such as layered oxides and polyanionic compounds, Prussian blue analogues (PBAs) have an open framework structure, allowing reversible two Na + storage and fast ion transportation, so that they have been extensively studied. , Moreover, compared with other cathodes synthesized at high temperature, the low-cost raw materials and facile room-temperature synthesis of PBAs will greatly reduce manufacturing costs and boost the practical application of SIBs in the future …”
