What is a battery separator?

The battery separator is one of the most essential components that highly affect the electrochemical stability and performance in lithium-ion batteries. In order to keep up with a nationwide trend and needs in the battery society, the role of battery separators starts to change from passive to active.

Will lithium-battery separators increase demand in 2020?

At the International battery Seminar & Exhibit in July, 2020, Avicenne Energy presented data that showed demand for Lithium-battery separators had increased from 0.4Bn m 2 in 2010 to 3.6Bn m 2 in 2020 and is projected to triple to 11.3Bn m 2 by 2030.

Which polyolefin is used to fabricate battery separators?

Two representative polyolefins, i.e. polypropylene (PP) and polyethylene (PE), are typically used for fabricating battery separators . Methodologies to fabricate battery separators are sorted into two methods: (1) wet method and (2) dry method .

Why is a battery separator important?

The major role of the battery separator is to physically isolate the anode from the cathode while allowing mobile Li-ions to transport back and forth . Unfortunately, two technical challenges associated with separator puncture and significant thermal shrinkage of polymer separators threaten the overall safety of batteries.

What electrolytes are used in a permawet membrane separator?

electrolytes such as propylene carbonate. to learn more about Celgard® PermaWet™ Permanently Wettable Separators. Celgard, a global leader in battery separator technology, develops and produces high-performance membrane separators used in energy storage applications.

What makes Entek a good battery separator?

When combined with ENTEK’s patented in-house ceramic coating technology (US Patent #9,847,519) the process enables the production of double-side coated, Lithium-ion battery separator nano-composites for maximum durability with exceptionally low thermal shrinkage of < 5% at 180 o C for 30 minutes.
