摘要： The present disclosure relates to an electrode stack for a lithium secondary battery, in which one or more positive electrodes and one or more negative electrodes are alternatingly stacked with a separator therebetween and insulation layers are formed on the outermost positive electrodes of the electrode stack. The insulation layers have an average thickness of 1 μm to 8 μm. The positive electrodes include a positive electrode collector; a positive electrode active material layer; and a protective layer including an inorganic compound. The protective layer is disposed between the positive electrode collector and the positive electrode active material layer. Additionally, an electrode assembly and a lithium secondary battery which include the electrode stack are also disclosed.
