Abstract 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 most common anodes for commercial Li‐ion batteries, a very capacity when used anode Na‐ion but they show reasonable capacities PIBs. The practical application graphitic materials in PIBs suffers from poor cyclability, however, large interlayer expansion/shrinkage caused by...
