1. Lithium-ion battery separator specifications:
Product Features:
Lithium-ion battery separator is a microporous film with color from white to beige. It is made of polyolefin resin through wet drawing process, which has good mechanical properties and chemical stability.
use:
It is used between the positive and negative electrodes of lithium-ion batteries to prevent short circuits.
We can also provide 18 20 25um diaphragm
2. Lithium-ion battery separator picture:
In the SEM photo, the magnification is 20000 times, the ruler is 1um, the aperture is uniform, and the diameter is about 0.1um.
The pore size distribution is between 100-1000 A, 0.001-0.1 um, and most are close to 0.03 um.
