Abstract

The present disclosure provides a negative electrode, a preparation method therefor, and an application thereof. In the process of preparing a negative electrode of the present disclosure, a graphite material is mixed with a graphene-coated silicon-oxygen material, and the graphene-coated silicon-oxygen material is prepared by means of spray drying. The present disclosure not only uses the advantages of graphite in cycle life and low-temperature capacity retention, but also makes full use of the advantages of the silicon-oxygen material, thereby reducing the areal density and compaction density of a negative electrode, thereby significantly improving the cycle life of a battery.
