摘要： According to an embodiment, there is provided a nonaqueous electrolyte battery. The nonaqueous electrolyte battery includes a positive electrode, a negative electrode, a separator sandwiched between the positive electrode and the negative electrode, and a nonaqueous electrolyte. The negative electrode contains a negative electrode active material having a Li-absorbing potential of 1 V vs. Li/Li+ or more. An electrical resistance of the negative electrode in a discharged state is within a range of 100 Ω·cm to 100000 Ω·cm. A pore volume ratio of pores having a pore diameter of 1 μm or more in the separator is more than 70%. The pore volume ratio is determined from a cumulative pore volume frequency curve of the separator obtained by a mercury intrusion porosimetry.

摘要： A nonaqueous electrolyte battery includes a positive electrode, a negative electrode and a nonaqueous electrolyte. The negative electrode contains a lithium compound and a negative electrode current collector supporting the lithium compound. A log differential intrusion curve obtained when a pore size diameter of the negative electrode is measured by mercury porosimetry has a peak in a pore size diameter range of 0.03 to 0.2 μm and attenuates with a decrease in pore size diameter from an apex of the peak. A specific surface area (excluding a weight of the negative electrode current collector) of pores of the negative electrode found by mercury porosimetry is 6 to 100 m2/g. A ratio of a volume of pores having a pore size diameter of 0.05 μm or less to a total pore volume is 20% or more.
