Popular Post Paul A Posted December 15, 2021 Popular Post Share Posted December 15, 2021 https://spectrum.ieee.org/solid-state-battery 25 October, 2021 Solid-State Batteries Rev Up Electric Cars, Boost Grid Storage. All-solid batteries could increase battery capacity, safety, and longevity. Now companies suggest they may commercialize solid-state batteries in the next five years for use in electric "hypercars" and power grids. Solid-state batteries instead employ solid electrolytes such as ceramics. Italian automaker Automobili Estrema is developing the Fulminea, which will feature four electric motors with a total peak power of 1.5 megawatts (2,040 horsepower), allowing the car to accelerate from 0 to 320 km/h (200 mph) in under 10 seconds. Its 100 kilowatt-hour battery pack will give it an expected range of about 520 kilometers (323 miles). "Currently our solid-state batteries have an energy density of about 400 watt-hours per kilogram, which is about double the typical energy density of commercial lithium-ion batteries on the market," Omar says. "By 2025, we aim to achieve an energy density of 450 watt-hours per kilogram." ________________ If solid state batteries become available in EUCs, won't need swappable batteries. Current EUCs will have double the range. Most powerful Ferrari has approximately 800 horsepower. 5 Quote Link to comment Share on other sites More sharing options...
Paul A Posted March 7, 2022 Share Posted March 7, 2022 Tiny solid state batteries. Could a few thousand in a pack be used for EUCs? Too cost prohibitive? Toyota has made a car operating on solid state batteries. https://www.caranddriver.com/news/a38711469/toyota-solid-state-batteries-2025/ Toyota announced that its first vehicle to use solid-state batteries will go on sale by 2025 in an interview with Autoline. The first Toyotas to use the new batteries will be hybrids, rather than fully electric vehicles, making it possible the first to get the new battery could be the Prius. 10 Jan 2022 Quote Link to comment Share on other sites More sharing options...
Paul A Posted March 31, 2022 Share Posted March 31, 2022 https://insideevs.com/news/551144/nissan-proprietary-solid-state-batteries/amp/ Nov 29, 2021 Nissan Announces Proprietary Solid-State Batteries: $75/kWh Pack They are expected by fiscal year 2028, with a pilot plant in Yokohama as early as fiscal year 2024. Not only that, Nissan says that by fiscal year 2028, it will launch an electric vehicle with "its proprietary all-solid-state batteries (ASSB)" and the ASSB pilot plant in Yokohama is expected to be ready as early as fiscal year 2024. Nissan says that the ASSB will reduce charging time to a third of its current value, double the energy density as well as make EVs more efficient and - probably the most important - more affordable.

Paul A Posted May 7, 2022 Share Posted May 7, 2022 A Vehicle equipped with all-solid-state batteries 44K views · 7 months ago Toyota Motor Corporation 35.7K subscribers In June 2020, we built a vehicle equipped with all-solid-state batteries, conducted test runs on a test course, and obtained driving data. Based on that data, we continued to make improvements, and in August 2020, we obtained license plate registration for vehicles equipped with all-solid-state batteries and conducted test drives. 2 Quote Link to comment Share on other sites More sharing options...

Paul A Posted May 7, 2022 Share Posted May 7, 2022 https://www.caranddriver.com/news/a38711469/toyota-solid-state-batteries-2025/ Jan 10, 2022 First Toyota with Solid-State Batteries Will Be a Hybrid The Japanese automaker confirmed that its first vehicle with solid-state batteries will launch by mid-decade and that the new tech will initially debut in a hybrid. Toyota announced that its first vehicle to use solid-state batteries will go on sale by 2025 in an interview with Autoline. The first Toyotas to use the new batteries will be hybrids, rather than fully electric vehicles, making it possible the first to get the new battery could be the Prius. Solid-state batteries promise to bring quicker charging times and longer ranges. https://www.motor1.com/news/559226/toyota-production-car-solid-state-battery-2025/ Jan 07, 2022 Toyota Confirms Production Car With Solid-State Battery On Sale By 2025 But why is Toyota prioritizing hybrids to the detriment of EVs? Gill Pratt admits it seems "a little bit unintuitive" at a first glance, but his explanation makes perfect sense. With the current crop of electric cars still carrying a substantial premium over their gasoline equivalents, fitting an EV with solid-state batteries would render the vehicle even more expensive. Costs are likely to come down between now and 2025, but not enough to make an ICE-less car with solid-state batteries feasible. For this reason, Toyota will be applying the promising tech to hybrids first since the batteries will be smaller and therefore won't have such a big impact on the asking price. 1 1 Quote Link to comment Share on other sites More sharing options...
360rumors Posted June 6, 2022 Share Posted June 6, 2022 CNBC posted a story that a manufacturer of solid state batteries is beginning a pilot production for EV cars. Could this help take EUCs mainstream? Not only could solid state batteries make EUCs cheaper but also lighter and more important, safer. I’m hoping they could be safe enough to bring on airplanes - in which case EUCs could become an essential traveling companion. https://www.cnbc.com/amp/2022/06/06/solid-power-begins-pilot-production-of-solid-state-ev-battery.html What do you all think? 1 1 Quote Link to comment Share on other sites More sharing options...
alcatraz Posted June 7, 2022 Share Posted June 7, 2022 (edited) I read an article that Sanyo/Panasonic just sent their first test shipment of 4680 cells to Tesla. When mass production kicks in you will start to see 4680 cells in wheels (I think). Current problem is heat dissipation. A larger cell has less surface area to dissipate heat from. Energy density is really good. Higher than 18650-3500 and 21700-5000. Now, it is likely that the cells will be manufactured in Japan but maybe in time also in China. Until they're made in China the availability will mainly be from recycled Tesla motors battery packs. They're usually sent to China for recycling.

goatman Posted June 7, 2022 Share Posted June 7, 2022 i used to think that but i found when testing batteries that the larger batteries like a 26650 or 21700 run cooler than a 18650 at 10 amp draw although it could have just been the cells that i was testing. i even had to stick one 26650 in a cardboard box with the lid closed to get it up to a good temperature to get good capacity out of it. i never really dove into it, i feel trapped like a chicken sitting on an egg when testing batteries, its not my cup of tea, but i think the 4680 and some other cells have multiple tabs inside 2 Quote Link to comment Share on other sites More sharing options...
Funky Posted June 7, 2022 Share Posted June 7, 2022 When these batteries become a reality in euc's, i will buy new euc then - as i said already many times. Be in 2-5 years. Can't wait. I don't really need "new" wheel, but safety that these "solid state" batteries give, are worth getting new euc. Worth not burning down house. Also same range for lighter wheels are a big plus for me. 3 Quote Link to comment Share on other sites More sharing options...

goatman Posted June 8, 2022 Share Posted June 8, 2022 (edited) nope at first i was testing to just test and learn and by the end of it all i found cell temperature, not C rate or amp draw, was more important some people dont want to see cell temps go over 25 celsius or more than 1C discharge i dont want a 30 pound battery pack. i chose 10 amps because you have these 18650 "10 amp" cells being life cycled tested at 1 C not 3C or 4C the high powered cells were being life cycle tested at like 5C or 8C but not 10 amps common battery packs are 4p and controllers at 20 or 40 amps, so 5 amp or 10amp/cell i never bothered with 1 C testing, there's alot of 1 C test data out there traction devices like PEVs will be fluctuating from what 5 to 60 amps and throw in some regen . a 4p pack of 5000 mah cells will be running anywhere from 0.25C to 3C and upto about 1C regen and might be ridden in hot temps and cold temps Edited June 8, 2022 by goatman Quote Link to comment Share on other sites More sharing options...

alcatraz Posted July 21, 2022 Share Posted July 21, 2022 I think we need Panasonic/Sanyo/Samsung/LG to start production long before solid state is cheap enough to be put in eucs. Quote Link to comment Share on other sites More sharing options...
Sary Posted July 22, 2022 Share Posted July 22, 2022 "Solid-state battery" is the most promising and most invested technology path, but in view of its many difficult bottlenecks in materials, preparation, cost, etc., the road to commercialization is a long way to go.

alcatraz Posted November 13, 2022 Share Posted November 13, 2022 The industry wants to write about news and get people excited. Truth is it could take a long time before prices to drop, regardless if it's available. Also, long term ownership is going to be a mystery for any early adopters. Progress is good but realistcally... it could take a while. 1 Quote Link to comment Share on other sites More sharing options...
