Overview of the Global and Chinese Lithium-Ion Battery Industry
Lithium-ion batteries are rechargeable batteries whose charging and discharging processes are achieved through the movement of lithium ions between the positive and negative electrodes. Compared to rechargeable alkaline batteries, lithium-ion batteries have higher energy density, longer service life, and better safety performance. Based on application scenarios, lithium-ion batteries can be mainly divided into three categories: electric vehicle batteries, energy storage batteries, and consumer electronics batteries, which are used in transportation vehicles, energy storage facilities, consumer electronics, and industrial machines.
In addition to the above core areas, lithium-ion batteries are also being applied more widely in emerging fields such as power tools, drones, robots, and the electrification of the COMMERCIAL AVIATION and maritime industries. As the world moves toward electrification, automation, and lightweight energy solutions, these areas are expected to become important growth drivers for the battery industry. The rapid expansion of lithium-ion batteries is unlocking vast new market potential, providing a solid foundation for the continuous demand growth of the entire battery supply chain, including high-performance battery separators. In increasingly diverse and high-specification applications, high-performance battery separators play a crucial role in ensuring safety, efficiency, and reliability.

The global lithium-ion battery industry volume increased from 576.0 GWh in 2021 to 2,278.9 GWh in 2025, with a compound annual growth rate of 41.0%. By 2030, the global volume is expected to exceed 6,500 GWh, with a compound annual growth rate of 23.6% starting from 2025. China remains the largest market, with the global lithium-ion battery volume increasing from 327.0 GWh in 2021 to 1,716.7 GWh in 2025, with a compound annual growth rate of 51.4%. By 2030, the volume is expected to exceed 4,500 GWh, maintaining a compound annual growth rate of 21.3%, and the global market share will exceed 65%. The volume of lithium-ion batteries in regions outside China is expected to exceed 2,000 GWh by 2030, with a compound annual growth rate of 29.6%, higher than in China, and its global market share will also increase to over 30%.
It is worth noting that due to the continuous penetration of new energy vehicles and the rapid adoption of energy storage, including user-side storage, the market share of lithium-ion batteries in Europe and the United States is expected to increase from 10.2% and 5.6% in 2025 to 13.3% and 6.6% in 2030. To address this trend, leading lithium-ion battery manufacturers are actively expanding production capacity in Europe and the United States, thereby accelerating the expansion and localization of the global lithium-ion battery supply chain, including the battery separator industry.
Part.04
Overview of the Global and Chinese Battery Separator Industry
Battery separators are polymer membranes. As essential components of lithium-ion batteries, separators prevent electrical short circuits and provide pathways for the movement of lithium ions between the positive and negative electrodes, thus having a significant impact on the performance of lithium-ion battery products.
Separators can be divided into dry and wet types. Dry separators are typically made of polypropylene (PP) or polyethylene (PE). Due to their high high-temperature self-sealing point and low thermal shrinkage rate, dry separators have high thermal stability, ensuring better safety performance. Wet separators are made of polyethylene (PE). With thinner thickness, better pore size distribution, and a wider adjustable porosity range, wet separators help the transfer of lithium ions between electrodes, enhancing the energy density of the battery. Coating processes can be applied to both dry and wet separators, significantly improving their thermal stability, puncture resistance, and safety performance. In wet separators, coatings are mainly used to improve high-temperature stability, which is crucial for high-energy-density batteries; while in dry separators, coatings focus on enhancing wetness, mechanical strength, and uniformity to meet the needs of cost-sensitive or high-temperature applications. Generally, about 80% of wet separators require coating, reflecting the high requirements for safety and performance in high-energy-density battery applications; about 20% of dry separators require coating, which aligns with their widespread use in cost-sensitive and medium-performance applications. This distribution highlights the critical role of coatings in wet separators, meeting the requirements for advanced battery performance.
