Abstract
The present application provides a binder and a lithium-ion battery including the binder. The binder is rich in amino groups, has strong alkali resistance and is not easy to decompose. Besides, rich amino groups in the binder are prone to form hydrogen bonds, so that the binder more fully coats an active material and can enhance an acting force between the active material and a current collector, improve a peeling strength of an electrode piece, and significantly improve a cycling performance, expansion rate, and rate capability of lithium-ion batteries using the binder.
