Abstract
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.
Claims11
