Li-Ion cell separator

Li-Ion cell separator

The separator is a semi-permeable membrane placed between anode and cathode of battery cell. Its main function is to separate the two electrodes of the lithium-ion cell and thus prevent electrical short circuits, while at the same time passing the lithium ions and allowing the electric charge to be transported.


We offer a simple polyethylene separator for basic research, in tape, with the following parameters:

  • Thickness: 16 ±2 µm
  • Tape width: 60 mm
  • Gas permeability: 350 - 550 sec/100ml
  • Porosity: 38 - 44%
  • Puncturing strength: >300 g
