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.
