For the record, a battery separator is a polymeric membrane positioned between the cathode and anode to prevent an electrical short circuit. The separator is a microporous layer which is dampened by the electrolyte serving as a catalyst to increase the movement of ions from one electrode to the other. Once the battery gets discharged, the ions move in the reverse direction. When the battery is getting charged, the ions move from cathode to anode. Here, the separator regulates the movement of ions between the positive and the negative terminals, thus it is primarily responsible for leakage of ions when the battery is supreme.
 

Based on product type, the worldwide battery separators industry from polypropylene segment amassed over USD 1.8 billion revenue in 2020 and is slated to grow with a strong CAGR over the forecast timeline. Extensive use of polypropylene in the consumer electronics sector due to its affordability is favoring the segmental expansion.
 

Speaking of battery type, lead acid battery segment is anticipated to record a CAGR of 16.2% over the analysis period. Traditionally, lead acid battery separators were comprised of polyolefins, cellulose, organic rubber, and polyvinyl chloride. However, modern lead acid batteries make use of polyethylene separators, a misnomer as these microporous separators require large quantities of precipitated silica to become acid-wettable.
 

Moving on to the end user spectrum, consumer electronics segment acquired of 25% of global battery separator market share in 2020 and is slated to witness a lucrative growth trend over the forecast timeframe.
 

The power storage segment held a market share of 5.6% in the same year and is likely to showcase significant growth over the study duration.
 

As per the geographical analysis, the Middle East held a 5% market share in 2020 and is likely to showcase lucrative growth trends over the analysis period.
 

Meanwhile, North America market is poised to expand at 15.2% CAGR through 2027, largely due to heightened investments in the automotive sector.
 

Prominent players influencing the worldwide battery separators industry trends are Bernard Dumas SAS, Targray Technology International Inc., Dreamweaver International, Sumitomo Corporation, Ube Industries Ltd., SK Group, Toray Industries Inc., Celgard LLC, and Asahi Kasei Corporation.
