“…Their structural formations are changed depending on the state of charge, from P2 to O3‐type structures. These structural evolutions occur with large volume expansion and finally lead to structure collapse with poor cyclability [70] . In turn, the tunnel‐type sodium manganese oxide structure shows high structural stability due to its special structural ordering.…”

Tunnel‐type sodium manganese oxide is attracting attention as a cheap and earth‐abundant cathode material for sodium‐ion batteries, offering more stable cycling performance than other layered materials due to its special structural ordering. Developments and applications in aqueous and nonaqueous electrolyte solutions are reviewed, and problems and possible solutions are discussed in detail.

“…More importantly, the widespread distribution of sodium makes NIBs a cost-effective alternative to LIBs, in particular for large-scale grid storage applications 3 – 5 . Substantial efforts have been devoted to the development and optimization of low-cost and high-performance electrode materials, in particular cathode materials 6 – 10 , to produce commercially viable NIBs.…”

Na-ion batteries have been considered promising candidates for stationary energy storage. However, their wide application is hindered by issues such as high cost and insufficient electrochemical performance, particularly for cathode materials. Here, we report a solvent-free mechanochemical protocol for the in-situ fabrication of sodium vanadium fluorophosphates. Benefiting from the nano-crystallization features and extra Na-storage sites achieved in the synthesis process, the as-prepared carbon-coated Na3(VOPO4)2F nanocomposite exhibits capacity of 142 mAh g−1 at 0.1C, higher than its theoretical capacity (130 mAh g−1). Moreover, a scaled synthesis with 2 kg of product was conducted and 26650-prototype cells were demonstrated to proof the electrochemical performance. We expect our findings to mark an important step in the industrial application of sodium vanadium fluorophosphates for Na-ion batteries.

There is a great appeal to develop an omnipotent player combining lithium-ion batteries (LIBs) with the capacitive storage communities. Hybrid capacitors as a kind of promising energy storage device are attracting increasing attention in the main playground in recent years. Unlike supercapacitors (SCs) and LIBs, hybrid capacitors combine a capacitive electrode with a Faradaic battery electrode. In these hybrid cells, the capacitive electrode brings the power while the energy mainly comes from the Faradaic one. Numerous efforts have been conducted in the past decades; however, the research about hybrid capacitors is still at its infancy stage, and it is not expected to replace LIBs or SCs in the near future utterly. Here, the advances of hybrid capacitors, including insertiontype materials, lithium-ion capacitors, and sodium-ion capacitors, are reviewed. This review aims to offer useful guidance for the design of faradic battery electrodes and hybrid cell construction. Brief challenges and opportunities for future research on hybrid capacitors are finally presented.
