Battery separators are a major component in batteries. Their main purpose is to isolate the negative and positive electrodes. They are porous membranes which are positioned between the electrodes of opposite polarity. They must obstruct any processes which negatively affect the electrochemical energy efficiency of a battery. This helps in avoiding electrical short circuits, while permitting rapid transportation of ionic charge carriers to complete the circuit during the transit of current in an electro-chemical cell. The global battery separator market is projected to reach USD 5.13 Billion by 2022, registering a CAGR of 12.5% between 2017 and 2022. The shift toward the use of sustainable fuel in the automotive industry has resulted in increasing the demand for EVs. The availability of smartphones and other electrical devices has increased due to the rising dependency on technology. All these are the key factors driving the battery separator market. However, the low heat resistance and safety issues related to batteries are inhibiting market growth.
Key companies profiled in this report are Toray Industry (Japan), Asahi Kasei (Japan), SK Innovation (South Korea), Freudenberg (Germany), Entek International (US), W-Scope Industries (Japan), Ube Industries (Japan), Sumitomo Chemical (Japan), Dreamweaver International(US), and Bernard Dumas (France). Rapid urbanization and increasing population in developing regions have encouraged companies to adopt several business strategies to stay competitive in the global battery separator market between 2013 and 2017. Therefore, the companies have adopted expansions, acquisitions, and new product launches as their key growth strategies in the global battery separator market.
Toray Industries (Japan), one of the largest battery separator manufacturers in the world, has adopted expansions as its key strategy. The company offers battery separators to numerous end-use industries, such as electric power storage, automotive, consumer electronics, as well as various other industrial uses such as forklifts, railway cars, and power tools, among others. As the demand for these separators has been increasing in the field of battery materials, the company has been focusing toward the addition of production capabilities in the Asia Pacific region. For instance, in October 2017, the company decided to spend USD 309 million on the expansion of its production capacity in South Korea. This move will help effectively serve the applications in electric vehicles and other industries.
Asahi Kasei (Japan) has considered expansions and acquisitions as its key strategies to stay competitive in the global battery separator market. Its in-depth product portfolio and good geographic coverage are its biggest strength. Asahi offers products under its popular brands, namely, Daramic, Hipore, and Celgard. The company has a broad product portfolio of battery separators for various batteries that are suitable for various applications. In March 2017, the company planned to increase the production capacity of one of its lithium-ion battery separator brand, Hipore, at a plant in Japan. Asahi Kasei also acquired a US- based company named Polypore International, Inc. in April 2015. Such development activities will strengthen and improve the company’s footprint worldwide.
