摘要：
Provided are a negative electrode for a nonaqueous electrolyte secondary battery, which has a current collector and a mix layer strongly adhered to each other and can increase a capacity of a nonaqueous electrolyte secondary battery, a fabrication method of the negative electrode and a nonaqueous electrolyte secondary battery including the negative electrode.The negative electrode for a nonaqueous electrolyte secondary battery includes a current collector and a mix layer provided on the current collector. The mix layer contains polyvinyl pyrrolidone having a K value in the range of 34˜112, carboxymethylcellulose, a latex binder and a negative active material. The carboxymethylcellulose is contained in a higher weight concentration than the polyvinyl pyrrolidone.
