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.
A unique capability of the proprietary ENTEK separator process is the ability to produce Lithium battery separator materials with ceramics intimately mixed within the structure of the base film separator. Such separators provide increased porosity, reduce impedance and increased wettability of benefit for larger ESS battery formats.
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.
If investment plans are approved ENTEK Membranes will become the UK’s first EV Lithium-ion battery separator producer and will allow the on-shoring and regionalisation of ENTEK’s proprietary separator technology throughout Europe.

ENTEK manufactures lithium-ion separators using a “wet” process. The molecular weight distribution of polyethylene, the percentage and type of plasticizer, extraction and drying conditions, biaxial stretch ratios, and annealing temperature are all factors that impact the final structure and properties of the separator.
UBE is one of the lithium ion battery separator manufacturers in the world was established in Tokyo in 1942, and its business scope covers mining, medical, building materials, machinery manufacturing, electric power and other fields, while chemicals and machinery are the company’s main business.
