>> You still haven’t addressed the basic issue...its the chemicals that contain the ions that need to be greater in size
Well, it IS “ABC” (All About Chemistry).
Just last night I was reading an article in Electronic Design News explaining the new markets for LiIon batteries (power tools, automotive); the difference in design constraints for automotive batteries (safety, not capacity, is paramount); and how new battery chemistries were achieving this (e.g. cobalt is a problem, and newer technologies found a way around using cobalt).
I found the same article online; if you’re technically inclined you may enjoy reading about it.

Once this comes out next year (if it does), then we'll find out what's wrong with it and what took so long.
Just like an internal combustion engine.
Check the story on the new thread I posted to you...........
>> I could have sworn mine was Lead-Acid
Your regular old vehicle — you know, the one that carried you to the “cathose” for your bonding sessions :-0 — prolly DOES have a lead-acid battery.
They must have been talking about “electric” vehicles.
LOL!!!!......................
We all know that would NEVER happen with a car that carries a tank full of volatile liquid.
Awesome news. Good for the environment, good for business, good for the consumer. Stupid PowerPoint slides from a fat, bearded liberal? Nope. Pissing and moaning from insane hyperenvironmentalists? Nope. Good ol’ American business know-how and scientific ingenuity? Ding, ding, ding.
I’m not surprised to see ExxonMobil investing heavily in research and development - they have quite a bit of money to invest and diversifying their energy offerings is always a good business move for a company of their size.
The amount of energy captured would be negligible. In full sunlight the best available solar panels now, sized to cover a car, would only deliver a few hundred watts and even at 100% efficiency could not produce more than a couple of thousand watts, so it would take weeks to fully charge a car's batteries that way. Even parking all day in full sunlight would not add more than a couple of miles to the vehicle's range.
They're making that claim about the battery type, not the battery size.
No, it’s the Rockefellers. Everyone knows you can’t have a good conspiracy without a Rockefeller involved.
I thought so too, but the Prius doesn’t have “toaster-sized” batteries, the individual cells are rectangular d-cells, put together into a rather large flat box (the previous Prius had round d-cells).
Have any car companies started using Nickel Metal Hydride for their 12-volt auxillary battery?
Oh have faith, that problems like that will be worked out in advance..........Geeesh..........
The fastest sports car available in the 0-60 race is an all electric car.
That is not what is said. They are using the technology of rechargeable lithium-ion batteries, like those found in cell phones and laptops. This will reduce the size of battery required to power a vehicle. They are not saying they will be the same size as a laptop.
>> I thought so too, but the Prius doesn’t have “toaster-sized” batteries
Then maybe it was just your typical “journalistic license”. They don’t need no stinkin’ fact-checking...
>> the individual cells are rectangular d-cells, put together into a rather large flat box (the previous Prius had round d-cells).
That’s interesting! If you ignore the warning and tear apart just about any NiMH “battery pack” (like from a cordless power tool) you find round cells — the individual cells are commercial off-the-shelf items that come from not-too-many manufacturers, and are assembled into proprietary “battery packs”.
Just a guess, but it sounds to me like Toyota took the same route — assemble COTS cells into a proprietary battery pack — rather than do battery R&D themselves, to get the car to market quicker.

Agreed.

Sounds like nothing more than a fancy capacitor.
Meh - only almost 2 years or so behind Fuji Heavy Industries (Subaru) and Nihon:
Tokyo, Feb 6, 2006 (JCN) - Fuji Heavy Industries (FHI), the manufacturer of Subaru vehicles, announced on February 6 that it has signed a five-year agreement to license its lithium ion capacity technology to Nihon Micro Coating.
Under the license agreement, Nihon Micro Coating will nonexclusively be able to develop, prototype, manufacture, use, and market lithium ion capacitors based on FHI’s capacity that uses its proprietary pre-doping technology to occlude lithium ions on a negative electrode to significantly increase the capacitor’s energy density.
Known for its expertise in coating, Nihon Micro Coating has manufactured lithium ion capacitor electrodes for FHI since 2002.
Given that lithium ion capacitors will have potential to be deployed in hybrid vehicles and replace automobile lead batteries, as well as find applications in consumer devices and industrial equipment, Nihon Micro Coating will work on the manufacturing of capacitor cells and the commercially producing lithium ion capacitors. In the meantime, FHI will also work with other companies to further research lithium ion capacitors.
