William Blair maintained an Outperform rating on Polypore International (NYSE: PPO). Analyst Brian Drab believes the company's battery will still be used in the Nissan Leaf, despite chemistry changing in 2014.

"Several recent articles highlighted comments made by Nissan officials regarding plans for a change in the Nissan Leaf’s battery chemistry/design in 2014. Reports indicate the change is being made, in part, to address performance issues in hot-weather environments," said Drab.

"The current Nissan Leaf battery pack contains single‐layer polypropylene separator material from Polypore (without ceramic coating). Our sources indicate the new battery design will include single‐layer polypropylene separator from Polypore, but now with an aluminum oxide ceramic coating. Ceramic coating is used, in large part, to improve thermal stability of the separator material," he added.
