Battery separators are critical components in batteries that prevent physical contact between the cathode and anode while allowing ionic flow, ensuring battery safety and performance. They are widely used in various battery types including lithium-ion, lead-acid, nickel-metal hydride, and others, playing a vital role in energy storage systems, electric vehicles (EVs), consumer electronics, and industrial applications.
The global battery separators market is expected to reach USD 26.63 billion by 2030, at a CAGR of 16.15% from 2022 to 2030.
