- Over the medium term, factors such as increasing adoption of electric vehicles, declining lithium-ion battery prices, and supportive government policies and incentives are likely to drive the market during the forecast period.
- Conversely, fluctuations in the prices of raw materials like polypropylene and polyethylene can impact the market during the forecast period.
- Nevertheless, technological advancements, particularly in nanotechnology, are making significant inroads into lithium-ion battery separators. Furthermore, the industry's shift towards sustainable and eco-friendly materials in battery production is not just a trend; it's a catalyst for innovation, paving the way for new market opportunities in advanced separator technologies.
China Lithium-Ion Battery Separator Market Trends
Polyethylene (PE) Material Type Segment is Expected to Dominate the Market
- In China's rapidly growing electric vehicle (EV) market, polyethylene (PE) separators are crucial components in lithium-ion batteries. Polyethylene separators enhance battery performance and safety because they are known for their excellent chemical resistance and mechanical properties. As the Chinese EV market expands, the demand for reliable and efficient energy storage solutions drives the widespread adoption of these separators in EV batteries.
- High-density polyethylene (HDPE) and ultra-high molecular weight polyethylene (UHMWPE) separators are emerging as leading choices for EV batteries in China. Their thermal stability is essential in preventing thermal runaway, a critical issue in battery systems.
- According to the International Energy Agency, in China, the combined sales of Battery Electric Vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs) increased from 13.8 million in 2022 to 21.9 million in 2023, reflecting a growth rate of 58.7 percent. This significant increase directly impacts the demand for lithium-ion battery separators, particularly polyethylene batteries.
- Recently, manufacturers have embraced cutting-edge production techniques and pioneered novel material compositions and chemistries. These advancements have not only improved the functional properties of Polyethylene separators but have also contributed to reducing manufacturing costs, making them an increasingly attractive option for electric vehicle manufacturers looking to optimize battery performance while managing production expenses.
- For example, in January 2024, researchers from the Institute of Modern Physics (IMP) under the Chinese Academy of Sciences (CAS), in collaboration with the Advanced Energy Science and Technology Guangdong Laboratory, unveiled high-temperature-resistant polyethylene terephthalate (PET) separators tailored for lithium-ion batteries. These separators play a crucial role in lithium-ion batteries, ensuring safety by insulating the cathode and anode to avert short-circuiting and enabling the seamless transport of lithium ions.
- Owing to the points mentioned, the polyethylene (PE) battery segment is expected to dominate the China lithium-ion battery separator market for electrical vehicle applications during the forecast period.

Adoption of Electric Vehicles is Expected to Drive the Market
- The rapid increase in the adoption of electric vehicles (EVs) in China is significantly driving the demand for lithium-ion battery separators. As more consumers and businesses transition to EVs, the need for reliable and efficient battery components becomes critical. Consequently, the lithium-ion battery separator market is experiencing substantial growth, fueled by the expanding EV market in China.
- China is making significant investments in lithium-ion battery separator projects. The country focuses on expanding production capacity and enhancing technology to maintain its lead in the global battery market.
- For instance, on June 20, 2023, Cangzhou Mingzhu announced plans to invest 3.5 billion RMB in constructing a wet-process lithium battery separator project in the Cangzhou High-tech District. This project involves building eight production lines and related facilities to produce 1.2 billion square meters of wet-process lithium-ion battery separators.
- Furthermore, in April 2023, Horizon completed the construction of its southwest base for lithium battery separator production in Tongliang, with a total investment of 6.5 billion RMB and covering an area of 560 acres. This facility has an annual output capacity of 2.5 billion square meters of wet-process base separators and wet-process coated separators. The project aims to extend the new energy storage industry chain in Tongliang, providing strong support for building a new energy storage industry highland in western China.
- The global reduction in lithium-ion battery prices amplifies the adoption of electric vehicles (EVs) in China, directly impacting the lithium-ion battery separator market. For example, according to Bloomberg NEF, the price of lithium-ion battery packs dropped to 139 U.S. dollars per kilowatt-hour in 2023, down from 160 dollars per kilowatt-hour the previous year. This price reduction makes electric vehicles more affordable, increasing the demand for efficient and reliable battery separators.
- Owing to the above points, China's adoption of electric vehicles is expected to significantly drive the lithium-ion battery separator market.
