Abstract
A method of generating a charge/discharge protocol of an additional charging/discharging operation included in an activation method with respect to assembled secondary batteries is provided. The method includes operation (a) of measuring a secondary battery thickness increase rate over time while repeating charging/discharging between a first voltage and a second voltage higher than the first voltage with respect to a first secondary battery; operation (b) of performing, at least once, an operation of performing operation (a) with respect to a second secondary battery after fixing the second voltage and changing the first voltage; operation (c) of determining one of first voltages except for a first voltage at a lowest rate from among measured secondary battery thickness increase rates as a lower limit voltage; and operation (d) of setting a protocol so that charging/discharging is repeated between the lower limit voltage and the second voltage.
