However, the much larger radius of the K ion poses challenges for the potassiation and depotassiation processes when the typical graphite-based anode is used, resulting in poor electrochemical performance. Thus, there is an urgent need to develop novel anode materials that are suitable for K ions. Herein, we develop a porous carbon material with high surface area derived from UIO-66-NH₂ metal-organic frameworks as an anode material instead of a graphite-based anode. The material is prepared using a double-solvent diffusion-pyrolysis method, which increased mesopore volume and average pore size, aRSC advancesUIO-66-NH₂-derived mesoporous carbon used as a high-performance anode for the potassium-ion battery.PMC86933962017YFB01029002147608851971094217761042016YFB01012012015A030312007Shen MLiu YLi XShao YZheng LPu ZLiao SHuang BfalseUIO-66-NH₂-derived mesoporous carbon used as a high-performance anode for the potassium-ion battery.As potassium is abundant and has an electronic potential similar to lithium's, potassium-ion batteries (KIBs) are considered as prospective alternatives to lithium-ion batteries (LIBs).
