Battery prototype: Two sludge-like electrode materials are fed into the device shown here. The anode material flows into the top half, and the cathode flows into the bottom. Lithium ions pass from one material to the other, and electrons flow through the black and red leads. Credit: Yet-Ming Chiang

“Batteries with a higher energy density would be smaller and cheaper, ...”
By definition, higher energy density means a smaller battery — however, it does not necessarily mean cheaper. For instance, lithium batteries have higher energy density than lead-acid batteries — they are also much more expensive.

Looks to me like MIT professor Yet–Ming Chiang, and the company he started, A123, is based on a lie.

I think the Chevy Volt is organic, by any definition it’s a lemon.

I believe they are normal size clips. The device is most likely a lab setup to demonstrate viability, and is probably the size of a matchbox....................

Yeah, post a title that says car battery and then show a penlight battery...nice bait and switch...it was a damned joke, son.

You win!!! You win!!! The chuckle of the day prize!!!!
Thanks soooooo much.
P.S. Is the photo-link publicly available for use??

Thanks for the link. Interesting read. What caught my eye in the original article was sufficient to call into question the viability of Mr. Chiang's claims.
Challenges remain before the battery can be commercialized. The electrical conductivity is still about 100 times less than it should be in a practical system, Chiang says. He's also working on increasing the concentration of active materials in the sludge.
They should have reworded it to "the battery's internal resistance is 100 times higher". Probably adequate for frying grilled cheese sandwiches, but not for an electric car.

Okay, okay, okay...it’s not worth arguing about even if it should have said “reduced scale prototype”......my comment was still a joke (both first and second times)......
