锂离子电池在电动车（EV）、储能系统（ESS）和消费性电子产品（CE）等各个领域发挥重要作用。因此，持续提升能量密度、寿命和安全性非常重要。为了满足这些需求，隔膜作为决定电池性能和稳定性的关键零件而备受关注。隔膜能够促进电解液中的离子传输，同时防止正负极之间的物理接触，避免内部短路。虽然隔膜被归类为惰性成分，但其热性能、机械性能和电化学性能会显着影响电池的稳定性、寿命和安全性。

如今，隔膜技术正透过各种材料和製程的开发不断进步。传统的聚烯烃基隔膜（PE、PP）因其优异的机械稳定性和耐热性而广泛应用。然而，其在高功率和高温条件下的性能受到限制。为了应对这些挑战，陶瓷涂层技术和基于不织布的隔膜已被引进，显着提高了热稳定性和耐久性。此外，固态电池等下一代电池的出现需要设计出突破传统限制的新型复合隔膜。特别是，采用PVDF（聚偏氟乙烯）和其他先进聚合物材料的隔膜因其优异的热稳定性和电化学性能而受到积极研究，这些性能符合下一代电池的要求。

随着隔板技术的进步，锂离子电池市场呈现快速成长态势。预计到2030年，全球隔膜市场规模将从2025年的约22亿美元增加至128亿美元，年复合成长率超过12%。电动车的普及和对储能系统（ESS）需求的不断成长是推动这一成长的主要动力。尤其是对高性能电池的需求，成为隔膜技术创新的催化剂。同时，各大厂商正加速隔板的研发，以配合固态电池等下一代电池技术。

Lithium-ion batteries play a crucial role in various sectors, including electric vehicles (EV), energy storage systems (ESS), and consumer electronics (CE). Consequently, continuous improvements in energy density, lifespan, and safety are essential. In meeting these demands, separators are gaining attention as a critical component that determines battery performance and stability. Separators allow ion transport through the electrolyte while preventing physical contact between the cathode and anode, thereby avoiding internal short circuits. Although classified as an inactive component, the thermal, mechanical, and electrochemical properties of separators significantly influence the cell's stability, lifespan, and safety.

Today, separator technology is advancing through the development of various materials and processes. Conventional polyolefin-based separators (PE, PP) are widely commercialized due to their excellent mechanical stability and thermal resistance. However, they exhibit performance limitations under high-power and high-temperature conditions. To address these challenges, ceramic coating technologies and nonwoven-based separators have been introduced, significantly improving thermal stability and durability. Additionally, the emergence of next-generation batteries, such as solid-state batteries, necessitates the design of new composite separators that surpass the limitations of conventional ones. In particular, separators utilizing PVDF (polyvinylidene fluoride) and other advanced polymer materials are being actively researched for their superior thermal stability and electrochemical performance, aligning with the requirements of next-generation batteries.

With the technological advancements in separators, the LIB market is experiencing rapid growth. According to SNE Research, the global separator market is projected to grow from approximately $2.2 billion in 2025 to $12.8 billion by 2030, achieving a CAGR of over 12%. This growth is primarily driven by the expansion of electric vehicle adoption and the increasing demand for energy storage systems (ESS). In particular, the demand for high-performance batteries is acting as a catalyst for innovations in separator technology. Simultaneously, major manufacturers are accelerating the development of separators tailored to next-generation battery technologies, such as solid-state batteries.
