Ltd, and Ube Industries Ltd, among others. Need More Details on Market Players and Competiters?
The Report Offers the Market Size and Forecasts in Terms of Revenue (in USD) for all the Above Segments. The Lithium-ion Battery Separator Market size is estimated at USD 6.37 billion in 2025, and is expected to reach USD 14.34 billion by 2030, at a CAGR of 17.6% during the forecast period (2025-2030).
Current separators, either in commercial usage or under the development stage, have yet to meet the high stability and lifespan performance standards necessary to prevent deterioration in the efficiency and reliability of battery technologies. This will likely create immense opportunities for the market studied during the forecast period.
Unlike other in top 5 lithium ion battery separator manufacturers in the world, Soteria's patented technology purportedly eliminates the root cause of thermal runaway, isolates short circuits, and allows batteries to continue to function after damage.
May 2023: SK IE Technology (SKIET) announced that the company had reached an agreement with the Chinese battery manufacturer - Sunwoda to supply separators for electric car batteries. Under the agreement, initially, the supply of battery separators would be limited to China and later extended to Europe.
