Polypore has the enabling technology that makes the world a better place.
You may not recognize Polypore by name, but chances are our products touch your life every day.
As a leading global high technology company specializing in microporous membranes, we bring advanced development and manufacturing know-how as well as unique problem-solving capabilities to your lithium-ion and lead-acid battery applications.
Polypore is the market leader in lithium-ion membrane battery separators for electric drive vehicles (EDVs) that include cars, buses and bikes. Our teams are also at the heart of product innovation in advancing lead-acid battery systems for idle stop-start vehicles that require a robust battery design where the engine is started at a higher frequency to simultaneously power all the auxiliary devices without interruption.
Lithium-ion and lead-acid batteries also play a critical role in energy storage systems (ESS) for storing and releasing power generated by wind turbines and solar panels. Lead-acid technology offers low maintenance, better cycling and improved charge acceptance, which is great in remote locations while lithium-ion technology offers a compact solution with high capacity and fast discharge rates. ESS applications have differing technical requirements that determine whether lithium, lead-acid or a combination of the two is the best option.
As more devices and technologies require advanced power options, there are also many specialty applications that rely on lithium and lead-acid innovation such as aircraft and drone batteries and ultra-capacitors. Some membrane variants also provide excellent properties for transdermal drug delivery and specialty textile applications.
