Aftertreatment process for a lithium secondary battery |
abstract |
There is provided an aftertreatment method for a lithium secondary battery comprising: an activation step of charging a heated lithium secondary battery to an activation voltage and holding the battery at the voltage, in a state in which the lithium secondary battery containing a positive electrode a nickel-rich (Ni-rich) lithium transition metal composite oxide having a layer structure containing 0.8 mol or more of Ni based on a total of 1 mol of transition metals as a positive electrode active material; a negative electrode; a separator disposed between the positive electrode and the negative electrode; and an electrolyte solution built into a battery case is heated, the activation voltage being equal to or higher than a voltage causing phase transition of the lithium-transition metal composite oxide. |
