Abstract
The present disclosure provides a lithium-ion battery, the lithium-ion battery comprises a positive electrode plate, a negative electrode plate, a separator and an electrolyte. The positive active material comprises a material having a chemical formula of LiNiCoMO, the negative active material comprises a graphite-type carbon material, the lithium-ion battery satisfies a relationship 58%≤KY/(KY+KY)×100%≤72%. In the present disclosure, by reasonably matching the relationship between the anti-compression capability of the positive active material and the anti-compression capability of the negative active material, it can make the positive electrode plate and the negative electrode plate both have good surface integrity, and in turn make the lithium-ion battery have excellent dynamics performance and excellent cycle performance at the same time.
