Abstract

The present invention relates to a positive electrode additive, a manufacturing method therefor, and a positive electrode and a lithium secondary battery comprising same. Specifically, provided, according to one embodiment of the present invention, is a positive electrode additive by which an imbalance in irreversible capacity between two electrodes may be canceled out, the 1st cycle charge capacity of the positive electrode may be increased, and the occurrence of gas in the battery may be inhibited.
