Polypore International Inc. (PPO)

[greasemoney]

One is Polypore (PPO), a North Carolina-based company that makes sophisticated filters and separators for use in lithium-ion batteries. According to analyst Craig Irwin at Wedbush Morgan, Polypore supplies the separators for the iPad’s li-ion battery (Polypore hasn’t confirmed this). Irwin’s revelation last week gave shares of PPO about a 10% boost. Cabot Green Investor subscribers bought Polypore in June, making the Apple connection a welcome bonus to what we already saw as a compelling investment.

That’s because lithium-ion batteries are the next generation of batteries that will eventually all but eliminate the lead-acid battery we use in most applications today. Li-ion batteries can be more fully charged more often than lead-acid batteries, lose their charge more slowly when not in use and are generally much lighter for the power they can store than comparable lead acid batteries. In the iPad, li-ions offer over 10 hours of operation on one charge, by some accounts.
