摘要:
A nonaqueous electrolyte lithium secondary battery obtained by the present invention has a separator and a porous layer which contains an inorganic filler and a binder and which is formed on the separator, wherein a thickness of the separator ranges from 12 μm to 18 μm, a porosity of the separator ranges from 52% to 67%, a thickness of the porous layer ranges from 3 μm to 15 μm, a porosity of the porous layer ranges from 44% to 70%, and the porous layer-attached separator exhibits a film resistance equal to or lower than 1.35 Ω·cm2 when impregnated with an electrolyte solution.
