Abstract

Abstract: The limited lithium resource in earth's crust has stimulated the pursuit of alternative energy storage technologies to lithium‐ion battery. Potassium‐ion batteries (KIBs) are regarded as a kind of promising candidate for large‐scale energy storage owing to the high abundance and low cost of potassium resources. Nevertheless, further development and wide application of KIBs are still challenged by several obstacles, one of which is their fast capacity deterioration at high rates. A considerable amount of effort has recently been devoted to address this problem by developing advanced carbonaceous anode materials with diverse structures and morphologies. This review presents and highlights how the architecture engineering of carbonaceous anode materials gives rise to high‐rate performances for KIBs, and also the beneficial conceptions are consciously extracted from the recent progress. Particularly, basic insights into the recent engineering strategies, structural innovation, and the related advances of carbonaceous anodes for high‐rate KIBs are under specific concerns. Based on the achievements attained so far, a perspective on the foregoing, and proposed possible directions, and avenues for designing high‐rate anodes, are presented finally. Abstract : The construction of suitable carbonaceous anodes is one of the core technologies to design high‐rate potassium‐ion batteries. Electronic conductivity and ion diffusivity of anodes are two key parameters. To realize a balance between these two parameters, many strategies of framework and morphology design for carbonaceous materials have been proposed. An overview of the design principles and typical advancements are presented in this article. Selected examples and perspectives on designing high‐rate anodes are stated.
