Disclosed are an electrode assembly, and a secondary lithium battery including the same. The electrode assembly is configured by alternately stacking two or more positive electrodes and one or more negative electrodes using a separator as a boundary therebetween, 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 formed on one surface of the positive electrode current collector, and a non-reversible material coating layer formed on the other surface of the positive electrode current collector and including lithium oxide, and the non-reversible material coating layer is positioned on an outermost surface of the electrode assembly.

Electrode assembly and secondary lithium battery including the same

A positive electrode, and a lithium secondary battery including the positive electrode, are provided. Specifically, the positive electrode may effectively counterbalance an irreversible capacity imbalance between two electrodes and further increase the initial charge capacity of the positive electrode by double-coating a positive electrode collector with a positive electrode active material and a lithium oxide-based compound.

Positive electrode and lithium secondary battery including the same

A positive electrode mix, a positive electrode, and a lithium secondary battery, each including the positive electrode mix, are provided. Specifically, the positive electrode mix includes lithium peroxide (LiO) and platinum (Pt), thereby effectively counterbalancing an irreversible capacity imbalance between both electrodes and further increasing the initial charge capacity of the positive electrode.

Positive electrode mix, positive electrode including the same, and lithium secondary battery

The present disclosure relates to a positive electrode for a lithium secondary battery comprising a positive electrode current collector and a positive electrode active material layer coated and formed on at least one surface of the positive electrode current collector, wherein the positive electrode current collector includes a non-coated portion protruded with no positive electrode active material layer coated thereon, and wherein an irreversible material composed of lithium oxide is coated on the non-coated portion, and a lithium secondary battery including the same.
