Colin, If i am correct Infinite Power solution was acquired by Apple. Sakti3 by Dyson, Seeo by Bosch. Is that right ? Seeo technology was developped to power electric cars and for storing energy in buildings. I guess Bosch is more trying to compete with Tesla technology on Automotive market.
STMicroelectronics has licensed the Oak Ridge technology too...but of course it is not a start-up company. Commercial product is EFL700A39...

Thanks for the tips on Quantumscape. They seem to have missed VW's July 2015 deadline for announcing their intension to use the technology (unless they are intensionally mum--but if so why announce you are making a decision by July 2015 and then let it pass by unannounced). The blog says from the patent filing "this adds up to a battery with a solid-state electrolyte rather than a conventional liquid electrolyte" which sounds speculative but promising. I can't get the company to return my calls, which does not seem to be consistent will landing a big deal with VW--unless as you say they are in complete stealth mode. My guess is that they have a solution looking for a problem. Thanks again for the tip!

Here's an article about Quantumscape's technology, which does involve solid state electrolyte:

But, years after VW invested in them, I haven't heard a peep, which is pretty suspicious. Either they are in total stealth mode or their technology (like many new technologies) isn't working out as well as they had hoped.

Regarding cost, these guys will only tell me goals in terms of appliations. But in general, they usually start with military and medial applications so they can concentrate on just getting it to work no matter the cost. Once proven out, they turn to optimization steps to lower costs for high-volume applications. None of those mentioned are to that state yet (except maybe Cymbet which is 17 years old with over 70 million and counting in R&D).

As a product designer, it's helpful to hear about cost estimates (no matter what the answer is). For instance, if the company has no idea what the cost in volume will be, it's very far from commecialization. If they know a volume cost target, that number can inform us which applications make sense. For instance, high unit cost relative to normal batteries = medical, military, industrial while low cost = consumer goods.

I saw your point about flammable vesus inflammble after thinking about it for a minute. i guess inflammable should be non-flammable as you poing out. Thanks.

Minor point: flammable and inflammable mean the same thing.

Thanks for the comment. Amprius is using a silicon anode, like Ilika, but is printing it roll-to-roll fashion which to me is putting the cart before the horse in terms of developing a viable battery. They also do not mention using a solid-state electyrolyte. Likewise neither Pellion nor Quantumscape mention a solid-state electrolyte, thus none of them really belong in this story. (Also Quantumscape takes so long to bring a single web splash page with no information that I suspect they don't even have the money to host on anything but an old PC). Nevertheless, I've made queries to all three and will report back anything interesting. Again, thanks for the heads-up on these companies.

I always wondered what happened to Quantumscape. VW invested in them a few years ago.

And a company called Pellion, supposedly founded by MIT researchers, touts a new battery technology.

One more that looks interesting: Amprius

Thanks so much for the tips. I've already got them working on an interview timetable, and I'll make sure I ask the right question from the right people. Thanks again.
