“…Furthermore, the values of the full width at half maximum (FWHM) of the treated samples are determined from the XRD patterns, which are larger than that of pristine samples (Table S4 in the Supporting Information), corresponding to the smaller grain size. This smaller particle size facilitates the K + ion diffusion by shortening the diffusion time and providing more active site [43] upon electrochemical cycles.

kind of secondary batteries will find promising applications in large-scale energy storage. [3] Owing to the low-cost [4] and low standard potential [5] of potassium (K), KIBs could in principle offer cost-effectiveness and higher energy density, which would lead to a substantial advance in energy storage technology. The fast K + ion diffusion property provides the possibility of saving the charging time of KIBs as the next generation energy storage and transport devices. [6] Then compared with Na-ion battery (NIB), a huge advantage lies in the application of graphite anode for KIB, [7] which is not feasible for Na + insertion into the graphite. [8] And also, the weaker Lewis acidity of K + ions ensures smaller solvated ions, leading to the higher mobility and larger transference number in electrolytes and lower desolvation energy, which offers faster K + ion diffusion kinetics with regard to that of Li + or Na + ions. [4,9] Based on these advantages, many investigations on the available anode materials for KIBs, such as carbonaceous materials, [8a,10] oxides, [11] sulfides, [12] organic materials, [13] alloy, [5] prussian blue analogues, [14] etc., have been reported continuously in the past few decades, [2a,15] however, fewer studies are devoted to the development of cathode. Present cathodes could be summarized as the layered transition metal oxides, [16] polyanions and pyrophosphates, [17] prussian blue analogs, [18] nanostructured iron composite, [19] organic materials, [20] and other potential materials. Up to now, most of the available studies are working on screening for new electrode materials with enhanced electrochemical performance, while the underlying K storage and transport mechanism in the electrode materials is lack of exploration and comprehension. [2a,21] Therefore, studying the electrochemical behavior of potassium ions is very important for building a better KIBs system.In specific, alkali transition metal oxides (AMO 2 : A = Li, Na, K; M = Ni, Co, Mn, Fe, etc.) with layered structure have been widely studied as promising cathodes for rechargeable batteries, [22] because of the topotactic de/intercalation feature. However, the accommodation of the bulky K + ion is less favorable than that of Li + and Na + ion in such compact structures, [2a] which will plausibly hinder the K + ion diffusion kinetics. [23] Previous reports [16e,24] have shown the sluggish diffusion performance of K + ions in KIBs with alkali transition Novel and low-cost rechargeable batteries are of considerable interest for application in large-scale energy storage systems. In this context, K-Birnessite is synthesized using a facile solid-state reaction as a promising cathode for potassium-ion batteries. During synthesis, an ion exchange protocol is applied to increase K content in the K-Birnessite electrode, which results in a reversible capacity as high as 125 mAh g −1 at 0.2 C. Upon K + exchange the reversible phase transitions are verified by in situ X-ray diffraction (XRD) characterization. The underlying mechani...

Sodium-ion batteries have been emerging as attractive technologies for large-scale electrical energy storage and conversion, owing to the natural abundance and low cost of sodium resources. However, the development of sodium-ion batteries faces tremendous challenges, which is mainly due to the difficulty to identify appropriate cathode materials and anode materials. In this review, the research progresses on cathode and anode materials for sodium-ion batteries are comprehensively reviewed. We focus on the structural considerations for cathode materials and sodium storage mechanisms for anode materials. With the worldwide effort, high-performance sodium-ion batteries will be fully developed for practical applications.

“…Until now, a large number of vanadates have been reported, and most of which have been studied for Li + storage. Recently, considerable new vanadate phases were identified to display promising electrochemical properties for metal‐ion batteries beyond Li, such as CaV 4 O 9 for Na + storage, Mg 0.3 V 2 O 5 · 1.1H 2 O for Mg 2+ storage, and Zn 0.25 V 2 O 5 · n H 2 O for Zn 2+ storage . The big family of vanadates with large amounts of members is as a result of the rich chemical valence state of vanadium and facile distortion of V–O polyhedra.…”

“…Apart from acting as pillars in the layered structure to improve the performance of a cathode, the Ca 2+ ions (or other alkali earth metal ions) can also bring a different positive effect in the conversion‐reaction based anode materials. Recently, Xu et al identified the outstanding electrochemical properties of alkali earth metal vanadates as SIB anodes. The prepared CaV 4 O 9 nanowires was found to display superior Na + storage performance compared to the control sample VO 2 nanowires, including an applicable reversible capacity over 300 mAh g −1 ( Figure a), a good rate capability and an excellent long‐term cycling stability over 1600 cycles.…”

The emerging electrochemical energy storage systems beyond Li‐ion batteries, including Na/K/Mg/Ca/Zn/Al‐ion batteries, attract extensive interest as the development of Li‐ion batteries is seriously hindered by the scarce lithium resources. During the past years, large amounts of studies have focused on the investigation of various electrode materials toward emerging metal‐ion batteries to realize high energy density, high power density, and a long cycle life. In particular, vanadium‐based nanomaterials have received great attention. Vanadium‐based compounds have a big family with different structures, chemical compositions, and electrochemical properties, which provide huge possibilities for the development of emerging electrochemical energy storage. In this review, a comprehensive overview of the recent progresses of promising vanadium‐based nanomaterials for emerging metal‐ion batteries is presented. The vanadium‐based materials are classified into four groups: vanadium oxides, vanadates, vanadium phosphates, and oxygen‐free vanadium‐based compounds. The structures, electrochemical properties, and modification strategies are discussed. The structure–performance relationships and charge storage mechanisms are focused on. Finally, the perspectives about future directions of vanadium‐based nanomaterials for emerging energy storage devices are proposed. This review will provide comprehensive knowledge of vanadium‐based nanomaterials and shed light on their potential applications in emerging energy storage.
