Global Lithium-Ion Battery Separator Market - Share, Size, Outlook to 2028

Market Research Reports | Q1 2024 | Report ID: BR0171

About the Report

The lithium-ion battery separator market is expected to witness significant growth during the forecast period due to the increasing demand for electric vehicles. The market is highly competitive, with major players focusing on research and development activities to gain a competitive edge. The growing trend of renewable energy is expected to further drive the demand for lithium-ion batteries and separators in the future. 


Some of the Other Drivers:

  • Strict environmental restrictions to reduce carbon emissions from transportation and energy generation.
  • The rising population and digitalization are increasing the demand for consumer electronics.
  • Expanding global energy storage systems market


However, there are a number of restraints that can prevent the lithium-ion battery separator market from growing as much as anticipated in the upcoming years. The following are some of the major obstacles to the market for lithium-ion battery separators:

  • High production costs 
  • Lack of a strong raw material supply chain
  • Competition from alternative energy storage technologies such as solid state batteries, etc.
  • Concerns associated with safety and disposal of battery materials


Lithium ion battery market is currently dominating the battery market globally due to its rising applications. They power most of the devices that we carry around with us, such as Consumer Gadgets, Cell phones, Laptops, MP3 Players, Digital cameras, etc. Lithium batteries are among the most energetic rechargeable batteries available today because of their excellent energy-to-weight ratio. They get their name from lithium ions that move from the cathode to the anode during discharge and cathode during recharging.


The increasing market for li-ion battery technology has increased the demand for li-ion battery separators to improve properties, performance, durability & safety at an acceptable cost. The li-ion Battery separator is a separator that electrically insulates between cathode and anode to prevent an electric short circuit between the anode and cathode and also helps to reduce the heat production.


Lithium-ion Battery separators separate cathode (negative electrode) and anode (positive electrode) materials within a cell mechanically. These separators prevent short circuits between the battery's internal components. It also allows for maximum ionic conductivity during charging or discharging. Lithium-ion battery separators are designed to shut down the batteries in the event of overheating or short circuits because they are porous, chemically, and electrochemically stable to the electrolyte and electrode materials in a battery.


Electric vehicles have been growing in popularity, and the shift towards the manufacturing of EVs has been increasing the demand for lithium-ion batteries, which has, in turn, raised the need for lithium-ion separators. In recent years, the development of energy-storage devices with high energy and power densities has increased enormously. Thus, lithium-ion batteries are one of the most promising solutions for these storage systems. Thereby, it upsurges the use of lithium-ion battery separators and provides a positive environment for the market to grow. 


Lithium-ion Battery Separator Market Opportunities

  • The market for lithium ion battery separators comprises energy storage systems, medical equipment, and aerospace applications in addition to electric vehicles and consumer electronics. Battery manufacturers that can diversify their product lines to appeal to these various market sectors will have a larger consumer base and more room for expansion.


Industry Trends

  • The need for environmentally friendly and sustainable battery separators is rising as people become more conscious of the negative effects lithium-ion batteries have on the environment. Manufacturers are creating separators using biodegradable polymers and other sustainable materials.
  • Nanotechnology is increasingly being used in lithium-ion battery separators. By lowering the size of the particles and expanding the surface area, nanotechnology can enhance the performance and security of separators.
  • There is a growing need for high-performance separators that can provide better thermal stability, increased safety, and higher energy density due to the rising demand for electric vehicles and energy storage systems.


Lithium-ion Battery Separator Recent Developments

  • ENTEK International LLC (US-based producer of 'wet-process' lithium-ion battery separator material) in addition to its previously announced 1.4 billion square meters per year project that was chosen for a Department of Energy grant award, stated its ambitions to increase manufacturing capacity. In February 2023, contracts for 18 separator film production lines were made with Brückner Group USA.
  • Celgard, LLC, a subsidiary of Polypore International LP, announced that it had entered into a strategic alliance agreement with lithium-ion battery technology company C4V in February 2023. The alliance will advance the development of separator solutions for the lithium-ion battery market that are optimized for C4V's high-voltage bio-mineralized lithium mixed metal phosphate (BM-LMP) cathode material.
  • In November 2022, South Korea's Hyundai Motor Group inked an agreement with battery maker SK On Co, Ltd to source a set percentage of essential minerals for their EV batteries from the United States or a U.S. free-trade partner in order to qualify for new U.S. EV tax credits.
  • In January 2022, Entek Manufacturing announced the acquisition of long-time business partner Adaptive Engineering & Fabrication (AEF).
  • In March 2021, SK IE Technology Co. Ltd, a subsidiary of SK Innovation, has decided to build two new Polish plants for separators in Poland.
  • In March 2021, Asahi Kasei, a manufacturer of lithium-ion battery separators, plans to increase its production capacity of Li-ion battery separators at its plant in Miyazaki, Japan. ​


The automotive sector holds a significant share of the lithium-ion battery separator market due to increasing EV demand. Worldwide EV sales have remained high. In 2022, a total of 10,5 million new BEVs and PHEVs were delivered, representing a +55% increase over 2021. EV market share increased from 8.3% in 2021 to 13.0% in 2022.


Global electric vehicles sales


Electric vehicles (EVs) have become an essential part of the automotive sector due to environmental concerns and government norms. For instance, Volvo announced selling hybrid or EVs. BMW, Daimler, and Volkswagen had announced EV sales targets of 15-25% by 2025. Similarly many automobile OEMs have announced their EV targets to capture the market. Thus, lithium-ion batteries find implementation in electric vehicles using battery separators to improve the safety and life cycle. Thereby, the specific advantage of the battery separator lies in the capability of contributing to the enhanced safety of batteries owing to its distinct structure, thereby promoting its use for electric vehicles.


Regional Market Analysis

Asia-Pacific is expected to be the leading region in the li-ion battery Separator market during the forecast period, followed by Europe, North America, the Middle East, and South America.


With the rapid expansion of electric vehicles (EV) market and renewable energy market, the Lithium-ion Battery Separator Market demand is expected to increase, especially in China, India, South Korea, Japan, and Australia.


Asia-Pacific holds a significant share of the lithium-ion battery separators market due to an increased electric vehicle investment in consumer electronics, smart grids, and others.
