As a negative electrode material for a nonaqueous electrolyte secondary battery, a graphite material capable of absorbing and releasing lithium is used, and the negative electrode material is polyethylene, ethylene-vinyl acetate copolymer, ethylene-propylene copolymer, ethylene-propylene-vinyl acetate copolymer, It is bound by at least 1 sort (s) chosen from polypropylene. By using the negative electrode and having a rechargeable positive electrode and a non-aqueous electrolyte, the non-aqueous electrolyte having strong peeling strength of the negative electrode mixture, excellent handleability, high reliability in the mass production process, and excellent low-temperature discharge characteristics and cycle characteristics A secondary battery can be provided. |
