Global and China Lithium Battery Separator Industry Research Report, 2014-2016
The lithium battery cell is composed of cathode material, anode material, electrolyte and separator, of which, lithium battery separator as a high value-added material with the highest technical barrier among lithium battery materials accounts for about 15-20% of the battery cost. The main role of the separator is to separate the positive and negative electrodes of the lithium-ion battery, thus preventing two neighboring contacts from a short circuit.
