Abstract: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, in… Show more
