CATHODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, METHOD FOR PREPARING THE SAME AND LITHIUM SECONDARY BATTERY

A cathode active material for a lithium secondary battery is provided, including a lithium metal oxide that satisfies Equation 1 below. Charge transfer resistance R CT ≤ 30 Ω (in Equation 1, R is based on a value measured by electrochemical impedance spectroscopy (EIS) for a half-coin cell including a cathode to which the cathode active material is applied).
