“…[ 6 ] In only a few decades, lithium‐ion batteries (LIBs) have revolutionized technologies, enabling the proliferation of portable devices and electric vehicles, with substantial benefits for society. [ 7–9,10–13 ] The performance of rechargeable LIBs has improved steadily for two decades, however, as relative technology approaches fundamental limits, the pace of advance is slowing year by year. [ 14 ] Furthermore, the resources of lithium and cobalt [ 15 ] generally used in LIBs are very limited on the earth's crust.…”

Sodium‐ion batteries (SIBs) and potassium‐ion batteries (PIBs) are considered the next‐generation candidates for future energy storage systems to partially substitute commercial lithium‐ion batteries because of their abundant sodium/potassium reserves, cost‐effectiveness, and high safety. Polyanionic cathode materials are widely used in alkali ion batteries due to their stable structural framework, high thermal stability, excellent alkali ion diffusion kinetics, and adjustable working voltage. Generally, the polyanionic cathodes used for SIBs surpass PIBs in the aspect of energy density and cycle life in most cases, however, the PIBs also have their unique advantages that are seldom reported. To this end, the polyanionic materials are classified by the valence states of active metal sites, the storage mechanism of Na+ and K+ in different crystal structures is summarized, and the electrochemical performance between SIBs and PIBs is compared. Particularly, some unique advantages of polyanionic cathodes in PIBs, such as high working voltage, superior rate capability, and excellent capacity retention are revealed, and the possible reasons are discussed in detail. Finally, various viable solutions are proposed to improve the battery performance of polyanionic compounds for future development.

“…[8][9][10][11] Since the commercialization of LIBs, they have dominated the market for decades, particularly in electric vehicles and portable electronic products, because of their advantages, including high efficiency, long lifespan, and low maintenance costs. [12][13][14] However, traditional LIBs are expensive and have low energy density, thus limiting their applications. [15][16][17][18] Li metal is deemed the "ultimate negative electrode" for Li batteries owing to its superiorities, including lightweight (0.53 g cm −3 ), low electrochemical potential (−3.04 V), and excellent theoretical capacity (3860 mAh g −1 ).…”

Li and Zn metals are considered promising negative electrode materials for the next generation of rechargeable metal batteries because of their non‐toxicity and high theoretical capacity. However, the uneven deposition of metal ions (Li+, Zn2+) and the uncontrolled growth of dendrites result in poor electrochemical stability, unsatisfactory cycle life, and rapid capacity decay of batteries assembled with Li and Zn electrodes. Owing to the unique internal directional channels and abundant redox active sites of covalent organic frameworks (COFs), they can be used to promote uniform deposition of metal ions during stripping/electroplating through interface modification strategies, thereby inhibiting dendrite growth. COFs provide a new perspective in addressing the challenges faced by the anodes of Li metal batteries and Zn ion batteries. This article discusses the stability and types of COFs, and summarizes some novel COF synthesis methods. Additionally, it reviews the latest progress and optimization methods of using COFs for metal anodes to improve battery performance. Finally, the main challenges faced in these areas are discussed. This review will inspire future research on metal anodes in rechargeable batteries.

Solid‐state lithium metal batteries incorporating LiNixCoyMnzO2 (NCM) as cathodes are developed to meet the high‐energy‐density requirements of energy storage systems. Nevertheless, the process of plating and stripping of Li‐ions on lithium metal electrodes causes significant volume changes, in which ultimately degrade battery performance. In this study, an elastomeric electrolyte with special latitude‐longitude interwoven structure is designed and synthesized successfully, which is composed of a crosslinked phase as filler and a polymeric phase as skeleton. With the increase of polymeric phase, the electrolyte changes from an irregular wrinkle structure to latitude‐longitude interwoven structure. The optimal electrolyte ATPE‐1 with a predominant latitude feature demonstrates remarkable resilience of 800% stretchability and high room temperature ionic conductivity (1.72 mS cm−1). Therefore, the close contact and excellent compatibility with lithium metal anode enable the lithium symmetric cell with ATPE‐1 as electrolyte to maintain a stable and extended cycle life for over 2000 h. Additionally, the existence of the supramolecular interaction between the polymeric phase and crosslinked phase effectively increases the decomposition voltage of the electrolyte. A Li/ATPE‐1/NCM622 cell delivers superior rate performance under ambient conditions. This innovative elastomeric electrolyte offers a promising potential for the practical application in high‐performance solid‐state lithium metal batteries.
