Ceramic Coated Separators Market Report 2026

The ceramic coated separators market size has grown exponentially in recent years. It will grow from $1.78 billion in 2025 to $2.16 billion in 2026 at a compound annual growth rate (CAGR) of 21.1%. The growth in the historic period can be attributed to lithium ion battery commercialization, consumer electronics growth, polymer separator development, ceramic material innovation, battery safety regulations.

The ceramic coated separators market size is expected to see exponential growth in the next few years. It will grow to $4.59 billion in 2030 at a compound annual growth rate (CAGR) of 20.8%. The growth in the forecast period can be attributed to electric vehicle adoption acceleration, grid scale energy storage growth, high energy density battery demand, thermal runaway prevention focus, advanced separator manufacturing. Major trends in the forecast period include rising demand for battery safety materials, expansion of electric vehicle battery production, growing adoption in energy storage systems, advancements in ceramic coating technologies, focus on thermal stability enhancement.

The surge in electric vehicles (EVs) is anticipated to drive the growth of the ceramic coated separators market moving forward. Electric vehicles are automobiles powered partially or entirely by electricity, using rechargeable battery systems as their main energy source. This increase in electric vehicle adoption is driven by rising environmental concerns, with both consumers and governments favoring EVs to lower carbon emissions and address climate change. Ceramic-coated separators improve the safety and efficiency of electric vehicles by offering superior thermal stability and preventing internal short circuits in lithium-ion batteries. For example, according to a report published by Kelley Blue Book, a US-based Cox Automotive company, in January 2024, a record 1.2 million car buyers in the United States opted for electric vehicles in 2023, representing 7.6% of the entire U.S. vehicle market, up from 5.9% in 2022. Consequently, the rise in electric vehicle adoption boosts the growth of the ceramic coated separators market.

Key players in the ceramic coated separator market are increasing their domestic manufacturing presence to meet the rising demand for electric vehicles (EVs) and decrease dependence on imports. Expanding local manufacturing ensures a reliable, localized supply chain, reduces lead times, enhances national energy security, and promotes job creation - important benefits as demand for EV battery materials rises. For instance, in March 2023, ENTEK, a US-based lithium-ion battery component manufacturer, announced a $1.5 billion investment to establish a new production facility in Terre Haute, Indiana. This facility will produce ceramic coated lithium-ion battery separators, with expected capacity sufficient for 1.4 to 1.6 million EVs annually by 2027 during its initial phase. A second phase is planned to increase total production to 3.2 billion square meters, enough for 3.5 million EVs, marking ENTEK’s largest expansion and a strategic effort to strengthen the U.S. domestic EV supply chain.

In September 2025, I Squared Capital Advisors Group, a US-based investment firm, acquired a majority stake in ENTEK Technology Holdings LLC for an undisclosed amount. Through this acquisition, I Squared Capital aims to enhance domestic battery component manufacturing capabilities and support the reshoring of critical US battery production to improve supply chain resilience. ENTEK Technology Holdings LLC is a US-based manufacturing company specializing in the production of battery components, including separators and related materials, for advanced energy storage solutions.
