- Summary:Potassium-ion batteries have attracted attention because of their abundant resources and similar electrochemistry to Li-ion batteries (LIBs). In the present work, GeSe/black phosphorus (BP) heterostructures as promising anode materials for K-ion batteries (KIBs) have been systematically investigated by firstprinciples calculations. The results reveal that GeSe/BP exhibits a semiconductorto-metal
transition after incorporating K atoms, indicating enhanced conductivity compared to monolayer GeSe. The energy barrier for K atom diffusion on GeSe/ BP surface is relatively lower than that on monolayer GeSe. In addition, the GeSe/BP heterostructure can accommodate up to five layers of K atoms with negative adsorption energy, which greatly improves the storage capacity. Hence, the GeSe/BP heterostructure has great potential for application in advanced electrode materials in KIBs. - Co-author:C. He, J. H. Zhang, W. X. Zhang, and T. T. Li
