Abstract

The present disclosure provides a negative electrode sheet and a lithium-ion battery including same. A negative electrode active material, a conductive agent, a binder, and an auxiliary agent (a compound represented by Formula 1) are used in the negative electrode sheet of the present disclosure, the above substances are dissolved in a solvent, uniformly mixed, and coated on a surface of a negative electrode current collector, after drying, the negative electrode sheet of the present disclosure can be obtained. The auxiliary agent (the compound represented by Formula 1), due to its small molecular weight and short polymer chain segment, can be fully mixed with the negative electrode active material, conductive agent, and binder.
