Insights and Trends of North America Lead-acid Battery Separator Market For SLI Applications
Polyethylene to Witness Significant Growth
- In recent years, North America's lead-acid battery separator market has increasingly turned to polypropylene, particularly for Starting, Lighting, and Ignition (SLI) applications. This adaptable thermoplastic polymer boasts key attributes: superior chemical resistance, robust mechanical strength, and commendable electrical insulation.
- Polypropylene's inherent versatility facilitates the integration of diverse additives and surface treatments. These enhancements not only boost performance but also prolong battery life. Such adaptability positions polypropylene as a prime choice for battery manufacturers aiming to elevate their products' efficiency and longevity. With the automotive sector under mounting pressure to deliver efficient and eco-friendly vehicles, the appetite for high-performance SLI batteries has surged, further entrenching polypropylene's role in the separator market.
- As automobile manufacturing in North America ramps up, so too does the demand for SLI batteries, amplifying the need for polypropylene in battery separators. This uptick is largely fueled by the rising production of electric and hybrid vehicles, which necessitate efficient and durable battery components. Moreover, strides in battery technology are intensifying the call for premium polypropylene separators.
- According to the International Organization of Motor Vehicle Manufacturers, North American automobile production has not only rebounded past pre-pandemic figures but is also on an upward trajectory. For instance, between 2022 and 2023, the growth rate was approximately 9.3%, underscoring the automotive industry's expansion.
- Research and development are actively honing in on polypropylene separator technology. Key focus areas encompass the creation of nanocomposite materials and sophisticated surface modifications, all aimed at amplifying the already stellar capabilities of polypropylene separators. These advancements seek to elevate battery performance, extend longevity, and bolster safety, aligning with the dynamic demands of the automotive sector and other industries dependent on lead-acid batteries.
- As a testament to the industry's innovation, ENTEK International LLC was awarded the 2024 BCI Innovation Award in April 2024 for its pioneering solvent-free separator technology, heralded as a greener alternative that doesn't skimp on strength or performance.
- Given these developments, the segment for polypropylene separator materials is poised for growth in the coming years.
United States of America is Expected to Dominate the Market
- In recent years, the United States market for lead-acid battery separators, primarily used in starting, lighting, and ignition (SLI) applications, has been on a steady growth trajectory. While these batteries play a pivotal role in internal combustion engine (ICE) vehicles, their usage in electric vehicles remains limited.
- As motor vehicle production in the country sees an uptick, the demand for lead-acid battery separators is set to rise in tandem. The International Organization of Motor Vehicle Manufacturers highlighted that 2023 production hit 10.61 million units, eclipsing the prior year's 10.06 million. Additionally, the government has rolled out various financial schemes to bolster automobile production. With this uptick in production, the need for lead-acid battery separators in SLI applications is anticipated to follow suit.
- Take, for example, the U.S. Department of Energy's (DOE) July 2024 announcement of a USD 1.7 billion investment. This funding aims to revitalize 11 shuttered or at-risk automobile manufacturing and assembly facilities across eight states—Michigan, Ohio, Pennsylvania, Georgia, Illinois, Indiana, Maryland, and Virginia. Such initiatives are poised to amplify the demand for lead-acid battery separators in SLI applications.
- As the nation intensifies its investments to steer its automotive sector towards electric vehicles (EVs), the appetite for lead-acid battery separators is set to rise, albeit slower than for internal combustion engine vehicles. Notably, most EVs utilize a 12-volt lead-acid battery for standby power. In 2023, battery-electric vehicles (BEVs) set a milestone in the U.S., crossing the one million sales mark, as reported by Argonne National Laboratory. This achievement marked a notable 55.4% surge from the previous year.
- In the future, as the demand for vehicles swells—particularly in the internal combustion engine segment that leans on lead-acid batteries for SLI systems—the market stands poised for growth. Furthermore, the rising adoption of electric vehicles, which utilize lead-acid batteries for their auxiliary systems, further strengthens this bullish outlook.
- As highlighted earlier, the United States is poised to lead the market in the coming years.
