Conventional Polyolefin Separator | 3DOM’s Separator |
---|---|
Irregular structure leads to dendrites, reducing lifespan and energy density. | ✓ Extremely stable structure – tightly-packed hexagon (3-D) structure makes it harder for dendrites to form, improving energy density, longevity, and safety |
40% porosity leads to low liquid retention, reducing energy density and longevity. | ✓ High porosity – high liquid retention of 72%, allowing for greater energy density and longevity. |
150~250C heat resistance. | ✓ Excellent heat resistance – 400C heat resistance. |
