Original Abstract Submitted
A method for charging and discharging a lithium secondary battery includes: a first step of preparing a lithium secondary battery including a positive electrode, a negative electrode and an electrolyte, with the positive electrode comprising lithium-rich manganese-based oxide having a manganese content of 50 mol % or more among all metals excluding lithium as a positive electrode active material; a second step of charging the lithium secondary battery from the lower limit voltage to the first upper limit voltage and discharging the lithium secondary battery from the first upper limit voltage to the lower limit voltage; and a third step of charging the lithium secondary battery from the lower limit voltage to the second upper limit voltage and discharging the lithium secondary battery from the second upper limit voltage to the lower limit voltage, wherein the second upper limit voltage is 0.05V to 0.20V higher than the first upper limit voltage, and the second step and the third step are alternately and repeatedly performed on the basis of a fixed number of times of cycles.
