Profile
ENTEK is a major manufacturer of battery separators, the microporous membranes that sit between the electrodes in a cell, and one of the significant separator producers worldwide. It supplies separators for both lead-acid and lithium-ion batteries.
The company produces multiple separator technologies, including AGM and polyethylene separators for lead-acid batteries and separators for lithium-ion cells, serving SLI, start-stop, deep-cycle, power and energy-storage applications. It designs and builds its own separator production lines with in-house engineering.
ENTEK is expanding lithium separator capacity, including in the United States, as domestic battery manufacturing grows, and also produces a range of other microporous membranes and functional materials.
