簡介目錄

鋰離子電池在電動車（EV）、儲能系統（ESS）和消費性電子產品（CE）等各個領域發揮重要作用。因此，持續提升能量密度、壽命和安全性非常重要。為了滿足這些需求，隔膜作為決定電池性能和穩定性的關鍵零件而備受關注。隔膜能夠促進電解液中的離子傳輸，同時防止正負極之間的物理接觸，避免內部短路。雖然隔膜被歸類為惰性成分，但其熱性能、機械性能和電化學性能會顯著影響電池的穩定性、壽命和安全性。

如今，隔膜技術正透過各種材料和製程的開發不斷進步。傳統的聚烯烴基隔膜（PE、PP）因其優異的機械穩定性和耐熱性而廣泛應用。然而，其在高功率和高溫條件下的性能受到限制。為了應對這些挑戰，陶瓷塗層技術和基於不織布的隔膜已被引進，顯著提高了熱穩定性和耐久性。此外，固態電池等下一代電池的出現需要設計出突破傳統限制的新型複合隔膜。特別是，採用PVDF（聚偏氟乙烯）和其他先進聚合物材料的隔膜因其優異的熱穩定性和電化學性能而受到積極研究，這些性能符合下一代電池的要求。

隨著隔板技術的進步，鋰離子電池市場呈現快速成長態勢。預計到2030年，全球隔膜市場規模將從2025年的約22億美元增加至128億美元，年複合成長率超過12%。電動車的普及和對儲能系統（ESS）需求的不斷成長是推動這一成長的主要動力。尤其是對高性能電池的需求，成為隔膜技術創新的催化劑。同時，各大廠商正加速隔板的研發，以配合固態電池等下一代電池技術。

本報告對全球鋰離子電池隔膜市場進行了研究分析，深入了解了鋰離子電池行業的現狀和未來發展趨勢，包括2021年至2024年的歷史需求資料、2025年至2030年的市場預測，以及各大隔膜廠商的最新產品趨勢和技術戰略。

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.
