%X Addition of different potassium salts into 1mol/L LiClO4/EC+DEC electrolyte can reduce the initial irreversible capacity loss at the first cycle and improve the reversible capacity and the rate capability of a natural graphite anode. Electrochemical impedance spectroscopy (EIS) and FTIR studies demonstrated the formation of a more conductive and thinner SEI layer on the graphite surface in the electrolyte containing a certain amount of potassium salt.
