Abstract
The present disclosure relates to a method of recovering a degenerated lithium battery cell, with the lithium battery cell being configured so that an electrode assembly including a positive electrode, a negative electrode and a separator interposed therebetween is impregnated with a non-aqueous electrolyte and embedded in a battery case, the method including: subjecting a lithium battery cell degenerated by 5% or more to a high temperature treatment for 1 to 6 hours at a temperature ranging from 60° C. to 100° C. in a fully discharged state.
