Environmental pollution and the energy crisis have promoted the development of clean energy as well as new‐generation energy storage systems. Potassium ion batteries (PIBs) have emerged as a possible alternative to lithium‐ion batteries due to their abundant reserves, low cost, and impressive electrochemical performance. However, the search for suitable cathode materials has become particularly crucial. Recently, Prussian blue (PB) has been investigated as a potential cathode material for PIBs, which has an open three‐dimensional framework to accommodate a large volume of potassium ions and adjustable composition for different applications. In this review, Prussian blue and its analogues (PBAs) and their application in PIBs were summarized detailly. We presented the composition, structure, potassium ion storage mechanism, preparation process of PBAs, and then focus on the performance optimization methods of the PBAs, including transition metal doping and conductive material adding into PBAs. Finally, the challenges as well as the outlook on the future development of PBAs were proposed for further application in this battery system.

“…This ingenious method not only effectively protects the prepared PW from oxidation but also obviates the need for an external inert atmosphere, thereby simplifying the synthesis process and concurrently driving down costs. In a separate advancement, Dai et al [52,68] used the technique of electrostatic spray-assisted co-precipitation under the safeguard of an inert atmosphere. This method yielded PBAs with high crystallinity: specifically, K While it's conventional to associate defects with impaired performance, the proper defects can be instrumental in imparting novel, superior functionalities to PBAs.…”

Recently, potassium‐ion batteries (PIBs) have emerged as a new energy storage system, offering a complementary solution to lithium‐ion batteries due to their cost‐effectiveness and significantly high theoretical energy density, making them suitable for large‐scale grid energy storage applications. The critical challenge PIBs face is the scarcity of appropriate high‐capacity cathode materials. Among the various contenders, Prussian blue analogs (PBAs) stand out. The appeal of PBAs arises from their simple synthesis, economic viability, and a stable, open framework conducive to the insertion/extraction of large‐size K+. This review aims to provide an overview of current research progress on PBAs as cathode materials in nonaqueous PIBs. A comprehensive examination of the crystal structure and electrochemical reaction mechanisms of PBAs is undertaken, with a focus on prevalent optimization strategies in PIBs. Subsequent sections delve into designing and developing potassium‐based full cells architectures incorporating PBAs. The discourse culminates in a discussion on the requirements for transitioning PBAs PIBs from a laboratory setting to commercial production, aiming to chart a course for the development of advanced PIBs.
