Potassium-ion battery, a key analog of lithium-ion battery, is attracting enormous attentions owing to the abundant reserves and low cost of potassium salts, and the electrochemically reversible insertion/extraction of the K-ion within the commercial graphite inspires a research spotlight in searching and designing suitable carbon electrode materials. Herein, five commercially available carbons are selected as the anode material, and the K-ion storage capability is comparably evaluated from various aspects, including reversible capacity, cyclability, coulombic efficiency, and rate capability. This work may boost the development of potassium-ion batteries from a viewpoint of practical applications.
