To provide a negative electrode for a non-aqueous electrolyte secondary battery that can be produced even without performing a heat treatment at a high temperature such as 2,000° C. or higher and can have the discharge capacity and the cycle characteristics (capacity retention) further increased.
The negative electrode for a non-aqueous electrolyte secondary battery according to the invention has a configuration in which a negative electrode active material layer containing a negative electrode material and a binder is formed on the surface of a current collector. Further, the negative electrode material has a core portion including carbonaceous negative electrode active material particles; and a shell portion including a polyimide and silicon-based negative electrode active material particles and/or tin-based negative electrode active material particles. Here, there is a feature that the content of the silicon-based negative electrode active material particles and/or tin-based negative electrode active material particles with respect to 100% by mass of the content of the carbonaceous negative electrode active material particles is 2% to 20% by mass. Furthermore, there is a feature that the binder is formed of a hydrophilic unit and a hydrophobic unit bonded together.
