Not much new here. Ghosn saying cheaper battery being manufactured now.
“There is a second generation of battery coming (online) now…which is less costly than the previous one,” Mr. Ghosn said in an interview Friday.
I'd say that's a REALLY significant story!
I noticed you're still working with polymers.

Cheaper isn't surprising. After all, they've built new factories, one would hope they would result in a cheaper battery. It's the better part that I haven't seen any indication of.

Or course, from Nissan's POV, cheaper is better...

Thanks! I Googled that second link and got it to come up. Here are a few tidbits:
WSJ Interview with Carlos Ghosn wrote: TOKYO--Nissan Motor Co. (7201.TO) Chief Executive Carlos Ghosn said that his company is working on improving the battery powering its Leaf electric vehicle, which may allow it to reduce prices and boost the eco-car's flagging sales.

"There is a second generation of battery coming (online) now...which is less costly than the previous one," Mr. Ghosn said in an interview Friday. "We are in a race in which you reduce the costs and adapt the price," he added.
WSJ Interview with Carlos Ghosn wrote:Nissan has sold more than 35,000 units of its five-door hatchback EV, which features a rechargeable battery instead of a gas engine, since its debut in late 2010. But the pace of Leaf sales has slowed recently, falling 50% from last year in August to just 685 vehicles in the U.S., where it sold a total of 9,674 units in 2011.

While demand from Americans has been sluggish so far this year, Nissan's CEO didn't back away from a 20,000 sales goal for the Leaf in the U.S. for the fiscal year through March.

"It's too early to (make a) call on the objective for the year, even though we recognize that the start of the year has been slow," he said, blaming a lack of charging stations and unease with new technology.

The company has forecast global sales for the Leaf of 40,000 in the current fiscal year and 1.5 million EVs by 2016 for both Nissan and its alliance partner, Renault SA, where Mr. Ghosn also serves as CEO and chairman.

Could "unease with new technology" be a euphemism for "worried about reports of premature battery aging"?

I wonder if the new battery tech will handle hot temps better?

Could this lead to larger batteries for the same price? Meaning more capacity? Just curious. Cheaper can be better after all, if this were the case.

It could, but only if the technology is improved to have a higher energy density. Just because they can make the batteries cheaper doesn't mean they can make them smaller or lighter. Otherwise, adding more would take up too much room and increase weight too much.
