Graphitic Carbon Nanocage as a Stable and High Power Anode for Potassium?Ion Batteries

As an emerging electrochemical energy storage device, potassium?ion batteries (PIBs) have drawn growing interest due to the resource?abundance and low cost of potassium. Graphite?based materials, as the most common anodes for commercial Li?ion batteries, have a very low capacity when used an anode for Na?ion batteries, but they show reasonable capacities as anodes for PIBs. The practical application of graphitic materials in PIBs suffers from poor cyclability, however, due to the large interlayer expansion/shrinkage caused by the intercalation/deintercalation of potassium ions. Here, a highly graphitic carbon nanocage (CNC) is reported as a PIBs anode, which exhibits excellent cyclability and superior depotassiation capacity of 175 mAh g?1 at 35 C. The potassium storage mechanism in CNC is revealed by cyclic voltammetry as due to redox reactions (intercalation/deintercalation) and double?layer capacitance (surface adsorption/desorption). The present results give new insights into structural design for graphitic anode materials in PIBs and understanding the double?layer capacitance effect in alkali metal ion batteries.
