It has been approved that embedding potassium ions into graphitic carbon interlayer is possible. The intercalation of potassium ions into graphite has been demonstrated feasible while the electrochemical performance of potassium ion battery (PIB) is still unsatisfying. Herein, an in situ formed NaCl...
