摘要 |
<p>Disclosed is a separator for energy devices, which hardly allows an internal short circuit, while excellent in electrolyte solution retention. Also disclosed is an energy device comprising such a separator. Specifically disclosed is a separator for energy devices, which comprises a nonwoven fabric laminate composed of two or more melt-blown nonwoven fabric layers arranged on top of one another. Each of the melt-blown nonwoven fabric layers has an average fiber diameter of 0.5-3 µm, and the weight per square meter of the nonwoven fabric laminate is not more than 50 g/m 2 . This separator for energy devices has a surface centerline roughness (Rt value) of not more than 35 µm.</p> |
