The Battery Separators market size is forecast to reach US$11.9 billion by 2027 after growing at a CAGR of 11.2% during the forecast period 2022-2027. Battery separators provide a barrier between the anode and the cathode of a battery to prevent electrical short circuits. The separator materials must be thin, porous, mechanically durable, chemically stable and electrically resistant. Most of the separators used to consist of a polymeric membrane forming a microporous layer. Commercially available lithium-ion batteries use polyolefin as a separator. Polyolefins are made from polyethylene, polypropylene or laminates of both materials. Polyimide separators are poised to be the best choice for high-end lithium-ion batteries. The growing popularity of electric vehicles drives the battery separators market. The surge in the demand for consumer electronics also acts as a driver.

Key Takeaways :
The Asia-Pacific region dominates the battery separators industry on account of the automotive and electronics industries in the region. According to India Brand Equity Foundation, the electronics industry size is expected to cross US$300-350 billion by 2025.
The market for microporous polymeric membrane separators has registered a spike in growth since the commercialization of lithium-ion batteries.
Conventional separators using polypropylene and polyethylene are prone to shrinkage and melting at 150 °C or above which may cause short circuits. Separators made of thermally stable polyimides are electrochemically stable and resistant to high temperatures and possess good mechanical strength, making them highly suitable for lithium-ion batteries.
The major opportunity for this market is the increasing R&D for new materials for battery separators.
