One embodiment of the present invention provides a nonaqueous electrolyte battery. This nonaqueous electrolyte battery is provided with a positive electrode, a negative electrode, a separator that is interposed between the positive electrode and the negative electrode, and a nonaqueous electrolyte. The negative electrode contains a negative electrode active material having an Li adsorption potential of 1 V vs. Li/Li+ or more. The negative electrode has an electrical resistance within the range from 100 Ω·cm to 100,000 Ω·cm in a discharged state. The separator has a pore volume ratio of more than 70% for the pores having a pore diameter of 1 μm or more. The pore volume ratio is calculated from the cumulative pore volume frequency curve of the separator as determined by a mercury intrusion method. |
