Of course not yet a battery. I like the fact that the tech was discovered accidentally.

$50M Battery500 consortium targeting battery pack with specific energy of 500 Wh/kg
http://www.greencarcongress.com/2016/07 ... ry500.html

It's interesting to note that IBM is an adviser to this 5-year project, as their original "Battery 500" project in 2009 was to develop a Li-air battery pack capable of providing 500 miles of range, a 10-fold increase in specific energy, while this is for a li-metal battery pack providing 500 Wh/kg., a much smaller step from the 170-200Wh/kg. Li-ion batteries typical today.

Considered giving this its own thread, but it's really just a different type of advanced battery, and has been discussed before. Via GCR:
Electric-drive cars should fuel, charging is 'dead end,' says NanoFlowcell
http://www.greencarreports.com/news/110 ... noflowcell

. . . Zero-emission cars powered by electric motors shouldn't use batteries that can be recharged, because a public charging network is "a dead end." Instead, they should use flow-cell batteries that can be "refueled" in minutes at centralized filling stations. . . .

The "dead end" quote is part of a longer statement by Nunzio La Vecchia, the Chief Technology Officer of NanoFlowcell Holdings, and inventor of the NanoFlowcell technology for energy storage. It's contained in a blog post, Full Speed Ahead Up a Dead End, on the NanoFlowcell website. . . .

If this tech can ever be commercialized, it would provide a hopefully cheaper alternative to building an H2 fueling infrastructure for FCEVs, while also providing BEVs with the rapid 'refueling' capability that they lack.

That's right. As with all of these future battery promotions, it is most important to look carefully at the figures-of-merit which aren't mentioned. Flow batteries have very similar benefits and drawbacks to H2 fuel cells:

Benefit:
- Fast refueling

Drawbacks:
- Low energy efficiency
- High vehicle cost
- High fuel cost
- Non-existent, expensive refueling infrastructure
- No home refueling, which makes all customers captive to the refueling system

Flow batteries have one benefit over H2 fuel cells: liquid rather than gaseous fuel.

NanoFlowcell has been a long running scam that has never demonstrated anything, in my opinion.

Pretty much what I figured, given the somewhat breathless nature of the claims. I've been following flowcell batteries for a while, so as with all new battery tech announcements (announced H2/FCEVs breakthroughs too) a large dose of cynicism is necessary.

I get into my BEV every morning, and drive to work.

It's nice.

I imagine you were aware that I was referring to announcements of new battery (and Fuel cell) tech, especially those involving major breakthroughs in performance or cost. Envia, anyone? I rarely bother to post anything in this thread, because announcements of lab results showing improved battery performance come out several times a week, and most of them never go further than the paper the announcement's referring to. NanoflowCell's an actual company, at least, albeit one which so far hasn't actually produced anything more than renderings and hot air AFAIA. Still, flow batteries are of interest.
