Potassium-ion batteries (PIBs) are attractive for grid-scale energy storage due to the abundant potassium resource and high density. The key achieving high-performance large-scale technology lies in seeking eco-efficient synthetic processes design of suitable anode materials. Herein, a spherical sponge-like carbon superstructure (NCS) assembled by 2D nanosheets is rationally efficiently designed K
