| 摘要 |
The present invention relates to a non-woven separator for a secondary battery. The non-woven separator makes it possible to manufacture a high power battery because size and distribution of pores of a non-woven fabric are uniform and resistibility thereof is excellent. According to the present invention, as a super fine filament and a fine filament are blended in the non-woven separator, the pores are evenly distributed inside the non-woven fabric and diameter thereof is uniform. Therefore, a battery using the non-woven separator has excellent resistibility and high power characteristics, preventing current leakage even in the case of high rate instant discharge (10 sec). |
