K-ion batteries(KIBs)have drawn much attention due to the abundant potassium reserves and wide accessibility as well as high energy density,which can be designed for large-scale energy storage systems.As the most promising anode materials for KIBs,graphitic car-bons,especially those with an intermediate structure between the crystalline graphite and amorphous carbons become a hot research focus because of the improved rate capability and enhanced diffusion-controlled capacity at low voltage regions.Herein,we first review the structures of graphitic carbons in the view of graphitic domains and the structure changes in their K-ion intercalation com-pounds.Then,we summarize the preparation mechanisms and characterizations of graphitic carbons and the influence factors in their degree of graphitization.Furtherly,we illustrate the strategies to optimize their K-ion storage properties from four aspects,namely graphitic domain design,microstructure engineering,electrochemical active component regulation,and defect engineering.Finally,we propose the issues that urgently need to be solved in gra-phitic carbons and the possible solutions.We hope that this view could offer some inspiration for the further designing and optimizing of graphitic carbons for practical KIBs.
