“…Lee and co-workers conducted the firstprinciples DFT calculations on the redox chemistry of the garnettype Mg 3 V 2 (SiO 4 ) 3 cathode, which showed that both anions and cations participated in the redox reactions and resulted in a high specific capacity of 356.52 mAh g −1 . [80] More importantly, the Mg 3 V 2 (SiO 4 ) 3 cathode could present a high average discharge voltage of 3.23 V versus Mg 2+ /Mg, corresponding to an ultrahigh energy density of 1152 Wh kg −1 . These findings further confirm the great potential of novel cathode materials based on O 2− an-ion redox chemistry in the development of high-energy-density MMIBs.…”

Rechargeable multivalent metal‐ion batteries (MMIBs) have garnered a surge of attention as competitive candidates for large‐scale energy storage applications owing to their high capacity, abundant resources, and good security. However, their practical implementation is still stuck at the prototype stage, mainly plagued with the lack of suitable cathode materials capable of reversible insertion/extraction of multivalent ions and the intrinsically complicated redox reaction mechanism. Recently, anionic redox chemistry has shown to be an effective strategy to increase energy density, providing a new research direction for the next generation of high‐energy rechargeable batteries. Unfortunately, anion redox chemistry has not received sufficient attention in MMIBs so far. Here, the fundamental principle and mechanism of anionic redox reactions in MMIBs are discussed and the recent advances regarding cathode materials based on cooperative cationic–anionic redox (CCAR) mechanism are summarized. Additionally, various advanced characterization techniques for studying the anionic redox process are highlighted, aiming to effectively illustrate the underlying reaction mechanism. Finally, challenges and perspectives for the future research on cationic–anionic redox chemistry in MMIBs are proposed. Insight into the significance of CCAR chemistry is provided here in MMIBs, presenting a new avenue for the development of high‐energy‐density cathode materials for MMIBs.

Rechargeable magnesium‐ion batteries (RMBs) have garnered increasing research interest in the field of post‐lithium‐ion battery technologies owing to their potential for high energy density, enhanced safety, cost‐effectiveness, and material resourcefulness. Despite substantial advancements in RMB research, a number of intrinsic challenges remain unresolved, such as the strong Coulombic interaction between Mg2+ and the host crystal structure of cathode materials, sluggish Mg2+ diffusion kinetic, poor electrolyte compatibility, and the formation of passivation films on the Mg anode interface. These issues hinder the commercial applications of RMBs. This review provides a comprehensive overview of the progress in key areas of RMB research, including representative magnesium‐ion storage cathode/anode materials and magnesium‐ion conducting electrolytes. Additionally, recent developments in electrode‐electrolyte interface regulations and pouch‐cell fabrication are outlined, highlighting current challenges and the implementation of effective solutions. Finally, future research directions are proposed to guide the development of high‐performance RMBs with practical applications.

Cathode materials are usually the key to determining battery capacity, suitable cathode materials are an important prerequisite to meet the needs of large‐scale energy storage systems in the future. Polyanionic compounds have significant advantages in metal ion storage, such as high operating voltage, excellent structural stability, safety, low cost, and environmental friendliness, and can be excellent cathode options for rechargeable metal‐ion batteries. Although some polyanionic compounds have been commercialized, there are still some shortcomings in electronic conductivity, reversible specific capacity, and rate performance, which obviously limits the development of polyanionic compound cathodes in large‐scale energy storage systems. Up to now, many strategies including structural design, ion doping, surface coating, and electrolyte optimization have been explored to improve the above defects. Based on the above contents, this paper briefly reviews the research progress and optimization strategies of typical polyanionic compound cathodes in the fields of lithium‐ion batteries (LIBs) and other promising metal ion batteries (sodium ion batteries (SIBs), potassium ion batteries (PIBs), magnesium ion batteries (MIBs), calcium ion batteries (CIBs), zinc ion batteries (ZIBs), aluminum ion batteries (AIBs), etc.), aiming to provide a valuable reference for accelerating the commercial application of polyanionic compound cathodes in rechargeable battery systems.
