Re: [EVDL] new battery technology moving past the labs
If you want to see a battery technology that is proven, safe, can take 50,000 cycles without much degradation and survive recharge cycles of 8 minutes, then look at Natron with their Sodium-Ion battery. Prussian Blue and seawater is essentially what their battery is made of. Unfortunately the energy identity is not ideal for cars, but Datacenters are very happy with their high cycle life battery! They are only a few miles from me and I visited them a few years ago, unfortunately it never came to a cooperation, not due to Natron. Cor.

Proposed solution that hits all your points, except one: Hot Air Batteries! No shortage of that on the world stage today, or ever. Sorry, no way can I see anything that involves politicians as being less expensive!!

Not hardly. Supplying a couple megawatts to a charging stop is just not that big of a deal. Your average shopping mall takes more than that, and even most residential distribution circuits carry more than that. 73 - Jim Walls - K6CCC j...@k6ccc.org ___ Address messages to ev@lists.evdl.org No other addresses in TO and CC fields UNSUBSCRIBE: http://www.evdl.org/sub/index.html CONFIG: http://lists.evdl.org/options.cgi/ev-evdl.org ARCHIVE: http://www.evdl.org/archive/ INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org
Re: [EVDL] new battery technology moving past the labs
> hundreds of thousands of cells allowing cars to recharge in less than > 10 minutes. It seems as if almost every electrochemist and lab working on batteries puts this at the top of the feature list. Why? Isn't fast charging at up to 350kW already possible with existing batteries? That much power can charge a 100kWh battery from 20% to 80% in 10 minutes. If you can get it! As I see it, the infrastructure required to blast that much power into multiple vehicles at a motorway charging stop is the big challenge. It's not the battery's ability to accept a charge. It's been a rule of thumb since about forever that with proper management an EV battery can charge about as quickly as it can discharge. So if you can send 350kW to the wheels, you can put 350kW back into the battery. But perhaps I'm missing something. We also already have capacity that we hardly dreamed of even a decade ago. Heck, back in 2000, 15kWh was a big battery. Today around 50-60kWh is common in garden variety EVs, and in the ignorant behemoths that the irresponsible car companies are pushing (just as they do in ICEVs), batteries are more like 70-90kWh, with some at least proposed that are over 100kWh. So I don't see that capacity is such a big problem any more. But again, maybe there's something here that I don't see. The world is growing more unstable by the day, with politicians waving flags and clubs, and pushing their nationalist belligerence. Present batteries use raw materials that raise political concerns. It seems to me that instead of worrying so much about charging speed, electrochemists should be concentrating their efforts on developing batteries that use raw materials that are more plentiful, more widely distributed, and less expensive.
