That and didn't they say it was a change to the separator (ceramic coated) and not necessarily a change to the chemistry?mwalsh said:I've found a problem with his story.
For example:
Polypore (PPO) Likely to Continue as Supplier for Nissan LEAF Battery
I wonder if Nissan is planning on making this change at the same time they increase production volume in the USA since separator supply is rumored to be one of the limiting to production volume.
Rumors are that Polypore may be losing the separator business to someone else as well when Nissan shifts to the ceramic coated separator as Polypore's price may be higher than the competition. Polypore Down 6% on Rumor It May Lose Big Auto Business (PPO)
What we really need is both the separator and a chemistry tweak to improve capacity. I would be really happy if I could get a replacement battery with even 15% more range and significantly better calendar life. Losing 15% (~10 miles) range in 2.5 years really hurts.
