Separator plays a vital role in lithium batteries for its safety, performance and cost. The term lithium batteries refer to the non-rechargeable, rechargeable lithium-ion batteries and lithium metal-based batteries are widely used in electronic devices. The primary function of the lithium-ion separator is to prevent the electric conduction between the anode and cathode while permitting ionic conductive via the electrolyte. It is manufactured from non-woven fiber, ceramic material and polymer films. It improves lifecycle and increase the performance of lithium-ion batteries. Porous membranes are generally used with these materials in manufacturing of lithium-ion battery separators due to their low manufacturing cost, improved mechanical properties and ability to prevent mixing of chemicals.
According to study, “Global Lithium-ion Separator Market Status (2015-2019) and Forecast (2020-2024) by Region, Product Type & End-Use” the key companies operating in the global lithium-ion separator market are Asahi Kasei Group, Toray Industries, Inc., SK Innovation Co Ltd.,Entek International LLC, Celgard, Sumitomo Chem, UBE Industries, Ltd.,Senior Tech, Evonik, Zhongke Sci & Tech, MPI, Cangzhou Mingzhu, W-SCOPE, Tianfeng Material, Jinhui Hi-Tech, Yiteng New Energy, Suzhou GreenPower, Hongtu LIBS Tech, DG Membrane Tech, Zhenghua Separator, Newmi-Tech, Huiqiang New Energy, FSDH, Gellec, Shanghai Energy.
Based on type, lithium-ion separator market is segmented into monolayer lithium battery separator, bilayer lithium battery separator and tri-layer lithium battery separator. Based on thickness, market is segmented into 16µm, 20µm and 25µm.Based on technique, market is segmented into wet process and dry process. The wet separator has twisted structure and interconnected microspores, which makes it more appropriate for use in long cycle life batteries, as it prevents the growth of dendrites while charging & discharging. Whereas, the dry separator has slit-like microspores and has straight & open porous structure, making it more suitable for high power density batteries. Based on technical indicates, market is segmented into thermal shrinkage, mechanical property, aperture size & distribution, automatic shutdown protection performance, porosity & electrolyte uptake and air permeability. Based on material used, market is segmented into polyethylene (PE), polypropylene (PP), nylon and others (nano-fibers and microfibers materials). In addition, based on application, market is segmented into consumer electronics, electric power storage, power vehicle and industrial use.
The lithium-ion separator market is driven by rise in demand for electrical vehicles (EVs), followed by rise in adoption of smart electronic devices, increase in government regulations related to carbon emissions for industrial and automotive sectors and growth in improvement in Li-Ion batteries. However, low heat resistance of separators and safety concerns related to usage of polyolefin separators may impact the market. Moreover, rise in use of batteries in energy storage devices is a key opportunity for market.
Based on geography, the Asian-Pacific region holds major share in lithium-ion separator market owing to growth in demand of smart phones & tables in developing countries in the region. Whereas, the European and North-American regions are projected to exhibit substantial growth rate due to significant improvement in consumer & manufacturing activities over the forecast period. In near future, it is expected that future of the market will be optimistic on account of growth InTechnology development in lithium-ion battery separators during the forecast period.
