This demo shows how standard battery separators shrink under heat, limiting fast charging and risking failure.
Next-Ion's separator stays stable at high temperatures — supporting 6-minute EV charging while improving safety and preventing thermal runaway.
Shown are 3 separators: Celgard (incumbent/competitor), Nanofiber (expensive separator), and Next-Ion.
The video demonstrates shrinkage of commercial separators as opposed to Next-Ion’s separator.
If a separator doesn’t shrink under heat, the battery can safely charge much faster. We use these separators in real cells to demonstrate ultra-fast charging performance —
