Porous polyimide film, separator for secondary battery, and secondary battery |
| abstract |
The present invention relates to a porous polyimide film, a separator for a secondary battery and a secondary battery. A porous polyimide film having a plurality of holes, the average flattening ratio of the plurality of holes is in the range of 0.1 to 0.7, and the coefficient of variation of the distance near the holes is in the range of 0.10 to 0.40, The surface and the back are communicated through the plurality of cavities. |
