Porous film, separator for electricity storage device, and electricity storage device |
| abstract |
The present invention provides a porous film having excellent followability of the separator to electrode expansion and contraction during charge and discharge and excellent charge and discharge cycle characteristics when used as a separator for lithium ion batteries. The porous membrane of the present invention is characterized in that the thickness when a load of 50 g is applied to a circular region with a diameter of 10 mm for 10 seconds is defined as the initial thickness t 0 , and the thickness when a load of 500 g is subsequently applied to the same region for 10 seconds is defined as t, when the load applied to the same area is changed to 50g, and the thickness after 10 seconds is set to t1 , the thickness change rate shown in formula (1) is 10% to 50%, and the thickness shown in formula (2) (t 1 ) The recovery rate was 80-99.9%. Thickness change rate (%)=[(t 0 -t)/t 0 ]×100? ? ...(1) Thickness (t 1 ) recovery rate (%)=(t 1 /t 0 )×100? ? …(2). |
