Provided are a binder and a lithium-ion battery comprising same. The binder is rich in amino groups, has strong alkali resistance and is not easy to decompose. In addition, the rich amino groups in the binder can form hydrogen bonds easily, such that the binder coats an active material more fully, the acting force between the active material and a current collector can be enhanced, the peeling strength of an electrode plate is improved, and the cycling performance, expansion rate and rate performance of the lithium-ion battery using the binder are also significantly improved. |
