摘要 |
A nonaqueous electrolyte battery includes a positive electrode (3), a negative electrode (4), a separator (5) and a nonaqueous electrolyte. The negative electrode (4) contains a negative electrode active material having a Lithium ion insertion potential of 0.4 V (vs. Li/Li + ) or more. The separator (5) is provided between the positive electrode (3) and the negative electrode (4). The separator (5) has a porosity of 50% or more and a pore diameter distribution in which a median diameter is larger than a mode diameter. The porosity and the pore diameter distribution are measured by mercury porosimetry. A surface roughness of the negative electrode (4) is larger than the mode diameter. |
