China Lead-Acid Battery Separator Market Trends
Rising Growth in the Automotive Sector Drives the Market
- China, bolstered by rising vehicle ownership, government backing for local manufacturing, and robust demand for commercial and passenger vehicles, retains its title as the world's largest automotive market. SLI batteries, pivotal for vehicle ignition and auxiliary functions, have solidified their status as the top choice in conventional and hybrid vehicles. This surge in SLI battery adoption fuels the market for lead-acid battery separators, vital components that enhance battery performance and longevity.
- In 2023, sales of passenger and commercial vehicles in China reached 26.06 million and 4.03 million units, respectively, marking increases of 10.61% and 22.2% from the previous year, as reported by the China Association of Automobile Manufacturers (CAAM). With major players in the industry launching various initiatives, automobile sales are set to grow further, aligning with the nation's surging demand for vehicles.
- For instance, in October 2023, Bosch Group, a leading German multinational, inked a deal to establish its strategic headquarters for commercial vehicles in Wuxi, underscoring its optimism towards China's push for new energy vehicles. Bosch envisions the project as a pioneering industrial park tailored for commercial vehicles, emphasizing technological advancements in vehicle electrification and assisted driving. These endeavors are anticipated to cater to the burgeoning demand for automobiles and the increasing need for battery separators in SLI applications.
- Even with the growing prominence of lithium-ion technologies, lead-acid batteries are a budget-friendly choice for SLI applications, particularly in the price-sensitive automotive market. A rising demand for dependable separators boosts battery efficiency and longevity. Recently, several companies have initiated projects poised to elevate automobile production in the near future.
- Take, for instance, Toyota Motor Corporation's June 2023 announcement. The automotive giant introduced a range of technologies, marking its shift towards becoming a key player in the battery Electric Vehicle (BEV) landscape. Toyota is set to roll out its next-generation BEVs in China and globally, with a full lineup slated for 2026. Looking ahead to 2030, the automaker's BEV Factory aims to produce 1.7 million units, a significant portion of the projected 3.5 million total. Such initiatives will likely boost the demand for SLI batteries and separators in the coming years.
- Manufacturers channel investments into R&D in China, focusing on advanced separators crafted from polyethylene (PE) and polypropylene (PP). These innovations enhance ionic conductivity and thermal stability and bolster resistance to acid degradation, aligning with the rigorous standards of contemporary vehicles during the forecast period.
- Therefore, as per the above points, rising growth in the automotive sector is expected to grow during the forecast period.

Polypropylene Segment to Witness Significant Growth
- The polypropylene (PP) segment is rapidly expands in China's lead-acid battery separator market, particularly for SLI (Starting, Lighting, and Ignition) applications. This growth is fueled by the surging demand for durable, cost-effective, high-performance separators, driven by the nation's burgeoning automotive and industrial sectors.
- As the world's largest automotive market, China boasts a robust demand for SLI batteries. Polypropylene separators, favored for their lightweight nature, high chemical resistance, and thermal stability, align perfectly with the performance requirements of contemporary vehicles, including Electric Vehicles (EVs). Notably, the sales share of EVs in China has seen a marked uptick in recent years.
- Data from the International Energy Agency (IEA) highlights that in 2023, electric vehicles constituted 38% of China's total automobile sales, a jump from 28% in 2022 to a mere 5% in 2019. With the Chinese government rolling out policies and incentives to further bolster EV adoption, this share is set to climb, amplifying the demand for SLI-type lead-acid batteries in these vehicles.
- In 2023, the Chinese government extended substantial subsidies for EV purchases, peaking at RMB 100,000 (approximately USD 15,000) per vehicle. Additionally, buyers of EVs benefited from exemptions on the vehicle purchase tax, underscoring the financial allure. Such initiatives are anticipated to elevate EV production and escalate the demand for lead-acid battery separators in the SLI application in the foreseeable future.
- Moreover, the growing emphasis on eco-friendly and sustainable materials in battery production drives the demand for polypropylene separators. Owing to advancements in material science, PP separators are now more efficient, boasting higher ionic conductivity, reduced resistance, and enhanced safety. This evolution aligns perfectly with the surging demand for high-performance SLI batteries.
- Consequently, the polypropylene segment is poised for significant growth in India, riding the wave of expansion in the automotive and energy storage sectors.
