Lithium-Ion Battery Separator Industry Dynamics

Development of the electric vehicles industry and rising interest in battery separators are playing as key drivers for market development. Electric Vehicles are picking up a reputation as a result of the increasing ecological concerns and the requirement for a supportable ecosystem in the automotive business. As a result of stringent government guidelines on industrial, automotive, and mechanical parts for carbon discharge, makers are moving towards lithium-particle batteries in vehicles and for modern applications which lead to the development of the lithium-particle battery separator market. Different nations have set strategies to decrease contamination levels by vehicle emanations. Cleaner, safer and simpler electric vehicles now span categories ranging from two-wheelers and rickshaws to cars and mining vehicles, as well as fleets of buses and vans.

For instance, Automobile giant Volkswagen has announced an investment of USD 24 billion to set up an all-electric line-up of cars, including infrastructure, by 2030. China's largest electric carmaker  BYD reportedly sold 113,669 new energy vehicles in 2017. Automaker Volvo has announced that electric vehicles will account for 50% of all its sales by 2025 and it plans to offer a hybrid variant of all its vehicles from mid-2019.

Low heat resistance of separators for high-performing applications such as electric vehicles is the key restraint hindering the market growth globally. On excessive heat, polyethylene layer melts and shut-down the battery by closing pores of the Li-ion separator, which restricts the transfer of ions.

Lithium-Ion Battery Separator Market Segmentation Analysis

Based on the application type, the lithium-ion battery separator market is segmented into industrial, electronics, automotive, and others. The electronics segment market is valued at USD Million in 2018 and is estimated to grow at a CAGR of % over the forecast period to reach USD Million by 2026. Electronics holds % of market share in 2018 and is expected to increase to % by 2026 in Global lithium-ion battery separator market. The lithium-ion battery industry is overwhelmingly meeting the electronics market demand globally, including cell phones, personal computers, and digital/video cameras. Lithium-ion batteries, found in nearly all consumer electronics and made almost exclusively in Asia. For instance, from 2001 to 2016, the value of electronics exports from Asia jumped from USD 537.3 billion to USD 1,758 billion, the growth rate is 8.2% each year on average.

ENTEK Lithium-Ion Separators is a leading producer of polyethylene separators used in lithium-ion primary and secondary batteries, with end uses ranging from portable devices to vehicles. ENTEK EP is used in secondary lithium batteries powering portable electronic devices such as laptop computers, tablets, mobile phones, and digital cameras. This product is also used in lithium-ion primary batteries for aerospace and the military.

By material type, the lithium-ion battery separator market is segmented into Polyethylene (PE), Polypropylene (PP), and Others. 

The Polyethylene separator is a micro-porous membrane, which prevents contact between the anode and cathode. The separator is made of polyethylene. In addition, the Polyethylene separator has a safety function called a shutdown. If the cell heats up accidentally, the Polyethylene separator melts due to the high temperature and fills its micro-porous to stop lithium-ion flow between anode and cathode. Having excellent thermal stability is the major driver for the polyethylene segment growth globally. As a single-layer polyethylene (PE) separator can tolerate a temperature of 130°C, so they are mostly used by the manufacturers in lithium-ion batteries.

Global Lithium-Ion Battery Separator Market Geographical Share

The Asia Pacific market is valued at USD Million in 2018 and is estimated to grow at a CAGR of % over the forecast period to reach USD Million by 2026. The Asia Pacific holds % of market share in 2018 and is expected to increase to % by 2026 in Global lithium-ion battery separator market. The Asia Pacific is expected to hold the largest market share globally. The Asia Pacific has been established as a center for the Electric vehicle market in recent years. Asia has several vertically integrated companies with 20 years of experience in making lithium-ion batteries, thus increasing the development of electric vehicles will drive the growth for lithium-ion batteries in the forecast period to 2026.
