description Disclosed is a negative electrode for a secondary battery, the negative electrode including: a negative electrode current collector; and a negative electrode mixture layer provided on the negative electrode current collector. The negative electrode mixture layer contains a graphite powder and a polymer electrolyte. A powder compact spring-back ratio of the graphite powder is 15 to 35%. Furthermore, disclosed is a secondary battery including: a positive electrode; the above-described negative electrode; and an electrolyte layer provided between the positive electrode and the negative electrode. Further, disclosed is a negative electrode material for a secondary battery, the negative electrode material containing a graphite powder and a polymer electrolyte.
