摘      要：With the diversified development of the battery industry,potassium-ion batteries(PIBs)have aroused widespread interest due to their safety and high potassium reserves on ***,the lack of suitable anode materials limits their development and application to a certain *** on first-principles calculations,we investigate the possibility of using PC_(3) monolayer as the anode material for ***_(3)sheet has excellent electrical properties and meets the prerequisite of anode *** storage capacity of potassium is as high as 1200 mAh·g^(-1),which is better than many other reported potassium-ion anode *** addition,the outstanding advantages of PC_(3)sheet,such as low diffusion barrier and moderate open-circuit voltage,make it a potential anode candidate for PIBs.
