    摘要: The present invention provides a nonaqueous secondary battery including a positive electrode, a negative electrode and a nonaqueous electrolyte. A porous layer containing an insulating material not reactive with Li is disposed on a surface of the negative electrode active material containing layer opposite to the side facing the negative electrode current collector or a binder in the negative electrode active material containing layer is polyimide, polyamideimide or polyamide; and the negative electrode current collector has a 0.2% proof stress of 250 N/mm2 or more or the negative electrode current collector has a tensile strength of 300 N/mm2 or more.
