Abstract

There is provided a negative electrode for a secondary battery that can provide a secondary battery having high charge and discharge efficiency, and a high capacity retention rate in charge and discharge cycles. A negative electrode for a secondary battery according to this exemplary embodiment contains scale-like graphite, a fluorine-based resin, and an imide-based resin. A method for manufacturing a negative electrode for a secondary battery according to this exemplary embodiment includes applying a negative electrode slurry containing scale-like graphite, a fluorine-based resin, an imide-based resin, and a solvent for dissolving the fluorine-based resin and the imide-based resin to a negative electrode current collector; and heat-treating the negative electrode current collector at a temperature of 100° C. or more and 150° C. or less.
