The battery separator market is anticipated to witness tremendous growth owing to rising investments in automotive sectors, wide-scale usage of polypropylene, and surging adoption of lead acid batteries. Increasing demand for efficient batteries in numerous end-use industries such as automotive, consumer electronics, and industrial among many others will also influence the business landscape.

A battery separator is essentially a polymeric membrane positioned between the negatively charged cathode and positively charged anode in order to prevent an electrical short circuit.

The separator is basically a microporous layer which is dampened by the electrolyte acting as a catalyst to surge the ions movement from one electrode to another. When the battery gets discharged the ions tend to move in the reverse direction. Whereas when the battery is being charged the ions move from cathode to anode. Here, the separator controls the various ions moving between the negative and positive terminal, thus it is mainly responsible for the leakage of ions when the battery is supreme.

The battery separator market is segmented in terms of product, battery, end-user, and regional landscape.

Based on product, the market for battery separator is classified into nylon, ceramic, PE, PP, and others. In 2020, polypropylene generated a revenue of over $1.8 billion and will exhibit strong growth over the coming years. Polypropylene is widely used in the consumer electronics sector largely because of its low price.

With respect to battery, the battery separator market is categorized into lead-acid, lithium ion, and others. Among these, lead acid battery segment will witness a respectable CAGR of around 16.2% over the projected time period. Earlier, lead acid battery separators included polyolefins, organic rubber, cellulose, and polyvinyl chloride. At present, most of the flooded lead acid batteries use polyethylene separators, a misnomer since these microporous separators need huge quantities of precipitated silica to be acid-wettable.

In terms of end-user, the overall battery separator market is bifurcated into power storage, industrial, consumer electronics, automotive, and others. In 2020, consumer electronics segment held a market share of around 25% and is anticipated to witness strong growth over the coming years.

The industrial segment is considered to be one of the most prominent end users of the battery separator market. The power storage segment accounted for a market share of over 5.6% in 2020 and is likely to foresee robust growth over the coming years.

From a regional frame of reference, North America battery separator is projected to witness a 15.2% CAGR over the forecast time period. This anticipated growth is ascribed to the rising investments in automotive sectors.

Meanwhile, in 2020, Middle East held a market share of 5% and is expected to showcase a healthy growth rate over the study time period.
