第14章 戦略的提言

第15章 調査会社について・免責事項

The Global Lithium-Ion Battery (LIB) Separator Market was valued at USD 6.84 billion in 2024 and is projected to reach USD 15.69 billion by 2030, growing at a CAGR of 14.67% during the forecast period. Lithium-ion battery separators are vital components that serve as physical barriers between the anode and cathode while permitting lithium-ion transport during battery operation. These separators, typically made from microporous polyethylene, polypropylene, or composite films, ensure battery safety, performance, and longevity. As demand for energy-dense and thermally stable lithium-ion batteries rises, separators have become focal points of innovation. The surge in electric vehicle production, coupled with growing reliance on consumer electronics and grid-scale energy storage, is accelerating demand for high-quality separator technologies that can meet performance and safety requirements across applications.

Key Market Drivers

Escalating Demand for Electric Vehicles Propelling Separator Requirements

The rapid global adoption of electric vehicles (EVs) has significantly boosted demand for lithium-ion battery separators. These separators are essential in ensuring safety by preventing internal short circuits while enabling efficient ion transfer between electrodes. With rising environmental regulations and government incentives pushing EV adoption, automotive manufacturers are ramping up battery production, which in turn increases the need for durable, heat-resistant separators. Advanced separators made from polyethylene or polypropylene, often coated with ceramic materials, are preferred for their thermal stability and mechanical resilience. As automakers strive for longer range and faster charging capabilities, innovations in separator design are becoming integral to achieving these performance goals.

Key Market Challenges

Technological Limitations in Thermal Stability and Safety Integration

A critical challenge for the LIB separator market lies in enhancing thermal stability without compromising ionic conductivity. Conventional separators made from polyolefins like polyethylene and polypropylene have low thermal thresholds, beginning to shrink at temperatures around 120°C and melting near 160-170°C. In high-energy-density battery systems, such as those used in electric vehicles and stationary energy storage, the risk of thermal runaway is amplified. Designing separators that resist deformation under high heat while maintaining optimal ion transport remains technologically complex. This challenge is compounded as battery technologies continue to push for greater energy density and thinner cell formats, raising performance and safety expectations for separator materials.

Key Market Trends

Rising Adoption of Ceramic-Coated Separators to Enhance Thermal Safety

A major trend reshaping the LIB separator landscape is the increasing use of ceramic-coated separators. Traditional polymer-based separators face limitations under high temperatures, which can lead to shrinkage and compromise safety. Ceramic coatings, typically comprising aluminum oxide or other inorganic oxides, improve thermal resistance and structural integrity of separators. These enhancements reduce the likelihood of internal short circuits during overheating events, thereby increasing battery reliability. Additionally, ceramic-coated separators offer better electrolyte wettability, mechanical strength, and puncture resistance-traits that are particularly valuable for high-performance EV batteries and grid storage solutions. As demand for safer, longer-lasting batteries grows, ceramic-coated separators are becoming a preferred solution across key end-user segments.
