New battery tech

Wed Oct 25, 2017 7:53 pm

There's an article on CNET about a new battery tech from Toyota that can recharge 3x faster than today's typical cells, and is supposed to retain at least 90% after 5000 cycles, or over 14-years at a daily recharge cycle. They plan to market it on one or more of their vehicles in 2019. Others have tried, and have had issues with reliability and reproducibility. We'll see how Toyota fairs with theirs. This could be a game changer.

On a different subject, the area rep at my dealer said that the electric X3 will have about 400-miles of range when it shows up in about a year. No idea, yet, if it will have a REx option.

Porsche has a new EV coming out in a couple of years that will be able to recharge quite fast and, this week, there was a consortium announced in Europe to start to deploy CCS units that will eventually be able to recharge at up to 350Kw/hr. combine that with batteries that can handle faster recharges, and you start to approach the convenience of refilling an ICE. Those CCS units still need some work, and the CCS standard needs some final agreements and tweaks. To transfer that much energy, they need liquid cooled pins in the supply plug and cable. FWIW, Porsche has a prototype up and operating near their headquarters so this isn't all vaporware.

Faraday has a prototype battery that exceeds the Toyota one by a significant factor if they can figure out how to produce it economically and in volume. Claim a significant charge is possible in as little as one minute! Now, a station capable of providing it would need to be HUGE, but being able to maintain near the max without having to taper off (much) would still be quite useful with today's and those 350Kw units in the pipeline.

Do you have a link ? I'm not doubting you, I just want to read more about it.

Sorry, it was not Faraday, but Fisker...

Faraday:
According to the release, the new collaborative battery is “the world’s highest energy density for a production automotive battery,”

Also from Faraday:
300+ Miles per Charge
Our lithium-ion battery cells achieve the world’s highest energy density – nearly double that of a production automotive battery. This not only represents a significant step forward in battery technology, it’s a tremendous increase in range, well in excess of 300 miles on a single charge.

The article mentions Fisker has a patent on the new battery technology. I searched the USPTO for patents and applications assigned to Fisker and didn't see a battery patent. Have you seen the patent, and if so, do you have the number ? I'm interested in "how it works" which should be somewhat disclosed in the patent.

Edit:
I found this on graphene batteries. Graphene is mentioned in the Fisker link so maybe that's what they're using. I would still be interested in reading the patent if someone can find it.
