Preparation method of positive electrode additive for lithium secondary battery and positive electrode additive for lithium secondary battery prepared thereby |
| abstract |
The invention relates to a method for preparing a positive electrode additive for a lithium secondary battery and the positive electrode additive prepared thereby. The positive electrode additive has high irreversible capacity and can prevent gelation and reduce gas generation. The preparation method of the positive electrode additive comprises the following steps: mixing a lithium raw material, a nickel raw material and an optional raw material containing an element M, and then heat-treating the mixture to prepare a predetermined lithium nickel oxide, wherein the lithium raw material Li 2 O and LiOH are included, and the amount of LiOH is 5 to 10% by weight relative to the total weight of the lithium raw material. |
