Electrode assembly and secondary lithium battery including the same

An electrode assembly configured by alternately stacking two or more positive electrodes and one or more negative electrodes with a separator as a boundary therebetween, wherein:

• outermost positive electrodes are positioned on outermost opposite surfaces of the electrode assembly, respectively;
• each of the outermost positive electrodes includes a positive electrode current collector, a positive active material layer disposed on one surface of the positive electrode current collector, and a non-reversible material coating layer disposed on an opposite surface of the positive electrode current collector and including lithium oxide as a non-reversible material;
• the non-reversible material coating layer is positioned on an outermost surface of the electrode assembly;
• the lithium oxide comprises one selected from the group consisting of Li2O2, Li2O, Li2NiO2, and mixtures thereof;
• and
• wherein the negative electrode includes a silicon (Si)-based material as a negative active material,
• wherein the non-reversible material coating layer further includes a catalyst.
