Abstract

A negative electrode piece and a secondary battery including the same. A type of polymer different from that in the prior art is selected as a component in the negative electrode piece, the polymer has high elasticity, high extensibility, can replace the polymer in the existing negative electrode piece, and can effectively improve and enhance the transmission performance of lithium ions and reduce the internal resistance of the lithium-ion battery. At the same time, it can effectively reduce side reactions caused by the expansion of the negative electrode piece, improve lithium conductive channels inside the negative electrode piece, and improve battery performance of the negative electrode piece during the battery cycling.
