Based on the latest market data, this article introduces the top 10 best Li-ion battery separator manufacturers in the world and discusses the performance of each enterprise in terms of technology.
Which battery separator company is still the leading player in the industry?
SEMCORP (wet process) is still the leading player in the battery separator industry. In 2022, Q1 battery separator shipments were 1.07 billion square meters, with a market share of 36.8%. Senior material (dry process + wet process) had a shipment volume of 360 million square meters in Q1 in 2022, with a market share of 14.9%, ranking second.
Founded in the US in 1984, Entek is the only lithium ion battery separator manufacturers in the world producing all three major separator technologies (PE, AGM and Lithium separators). It is also the world's leading designer and manufacturer of high-reliability microporous polyethylene battery separators for lead-acid and lithium-ion batteries.
The global battery separator shipment was 10.7 billion square meters in 2021. And the China mainland market accounted for 73.8% of the worldwide market share, which has an increase of 15% compared to 2020. In the first quarter of 2022, the national shipment capacity reached 2.8 billion square meters, equivalent to 35% of the shipments in 2021.
Among the top 10 separator manufacturers, Sinoma has been ranked third with solid ability in the past two years. The top three in the diaphragm industry still face challenges from 4-10 other battery separator companies.
The HIPORE™ lithium-ion battery separator developed by Asahi Kasei is made of a microporous polyolefin sheet. Not only does it not emit harmful gases during incineration, but it also prevents the anode and cathode from contacting each other and causing a short circuit, making it suitable for use in smartphones.
What is Soteria battery separator?
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.
