PROBLEM TO BE SOLVED: To produce and provide, in large quantities, batteries having a high rate discharge characteristic, in particular, having an excellent discharge characteristic at low temperatures. SOLUTION: In relation to a nonaqueous electrolyte secondary battery negative electrode 3 formed from a carbon material capable of occluding and releasing lithium as a negative electrode material and a binder, a nonaqueous electrolyte secondary battery negative electrode that has an excellent low temperature discharge characteristic, is provided with an electrode plate having large peel strength and is easy to handle can be provided by mixing and using, as the binder of the negative electrode material, one or more kinds of binders A selected from a polyacrylic acid or acrylic salt, polyacrylic methyl, polymethacrylic acid or methacrylic salt, polymethacrylic methyl, ethylene.acrylic acid or acrylic salt copolymer, ethylene.methacrylic acid or methacrylic salt copolymer, and a binder B selected from a styrene butadiene copolymer of which combined styrene quantity is not less than 80% and less than 100% or polystyrene. |
