Global Lithium-Ion Battery Separator Market 2025 by Manufacturers, Regions, Type and Application, Forecast to 2031

According to our (Global Info Research) latest study, the global Lithium-Ion Battery Separator market size was valued at US$ 3989 million in 2024 and is forecast to a readjusted size of USD 6727 million by 2031 with a CAGR of 7.6% during review period.

A battery separator is a polymeric membrane placed between the positively charged anode and negatively charged cathode to prevent an electrical short circuit. The separator is a microporous layer that is moistened by the electrolyte that acts as a catalyst to increases the movement of ions from one electrode to the other electrode. When the battery is charging the ions moves from cathode to anode and when the battery gets discharged the ions will move in the reverse direction. The separator controls the number of ions moving between the positive and negative terminal and hence it is responsible for the leakage of ions (self-discharge) when the battery is ideal. Although the ions pass through the separator freely it will not have any electrical conductivity and it always acts as an isolator.

Global lithium-ion battery separator key players include Asahi Kasei, Toray, SK Innovation, UBE, etc. Global 5 four manufacturers hold a share about 60%. China is the largest market, with a share about 45%, followed by Japan and South Korea, both have a share over 40%. In terms of application, the largest application is consumer electronics, followed by power vehicle, etc.
