世界のセパレーター市場は、過去3年間のCAGR (複合年間成長率) で、29.7％の成長を遂げました。
The global separator market has grown at a CAGR of 29.7% over last three years.
In recent years, the secondary battery market is extending into the ESS and EV market in the small IT application market, and demand for the secondary battery separator market is also expected to increase accordingly.
Asahi Kasei in Japan has been traditionally strong in lithium-ion secondary battery separator market, and it is expected to strengthen its influence due to the acquisition of Celgard (Polypore), which was ranked fifth in market share last year. Asahi Kasei is followed by SK Innovation in Korea, Toray, Ube, and Sumitomo in Japan. As the China battery market has grown, the market share of separator companies in China has increased as well.
Three countries such as Korea, China and Japan are leading the global separator market, and Japanese companies are coping with material superiority of China low price based on their advanced technology and patent advantages. SK Innovation and W-scope (foreign-funded companies) in Korea have been aggressively winning market share. The leading companies in secondary battery separator market are preparing for market demand growth through expanding production capacity.
In the lithium-ion secondary battery, separator materials are generally classified into wet and dry type. Asahi Kasei, Toray, and SK Innovation have mainly adopted the wet type. In contrast, Celgard, Ube have mainly adopted the dry type. In the meantime, separator of wet type has been widely used in the separator market for small IT devices. In case of separator of dry method, dry type has relatively better heat resistance than wet type. For this reason, recently a lot of secondary battery companies are currently reviewing dry type as automotive secondary battery separator. Therefore, demand is expected to increase. Additionally, it is expected to greatly increase demand for application of organic / inorganic / polymer coating separator, and composite separator into battery of the electronic car, where the safety is even more important instead of focusing on existing PE and PP when it comes to separator material.
In this report, we have looked through the overall functions and technology of the separator that determines the safety of the lithium-ion secondary battery. Thus, the latest heat resistance separator and coating separator products that have newly emerged have been covered. In addition, it includes production status and patent status by separator companies, market status of separator products, and forecasts for future expected market.
