Abstract:

Due to the limited non-renewable energy resources, the use of renewable energy is greatly affected by the environment, and it is imperative to develop a new generation of energy storage and conversion systems. Potassium ion batteries are very likely to become the next generation of large-scale commercial energy storage systems due to their advantages such as high energy density and low cost. Prussian blue analogues have attracted great attention due to their open three-dimensional frame structure and the ability to quickly deintercalate potassium ions. Derivatives synthesized with it as a template have been extensively studied. Based on the investigation of relative literature, this review introduces the structure of potassium ion batteries and Prussian blue analogs and their derivatives in detail, summarizes the advantages of potassium ion batteries, Prussian blue analogs and their derivatives, reviews the current status of the application of materials in potassium ion batteries, and give a detailed introduction to the performance of the cathode and anode materials. For cathode materials, it mainly introduces iron-based, manganese-based, other types and partial substitution of Prussian blue analogs and related modification strategies, focusing on the analysis of the charge and discharge mechanism of different types of materials; for anode materials, the Prussian blue derivatives through carbon modificated strategies are introduced, and the advantages and disadvantages of the traditional carbon anode materials are briefly summarized for comparison. Comprehensive analysis shows that through exploring synthetic methods, adopting partial substitution, introducing low-dimensional structures and other strategies, it is expected to enhance the future applications of Prussian blue analogs and their derivatives in potassium ion batteries.

Key words: potassium ion batteries, Prussian blue analogs, derivatives, cathode materials, anode materials
