Electric cars - What's the latest news for battery innovation?

Over the years I've seen many articles about major breakthroughs in battery technology that will make electric cars greener and more competitive with gasoline powered cars. What ever happened with those companies and their bold claims? When will there be electric cars that go more than 400 miles on a charge and take less than 15 mins to charge?

1. We're not too far away from that, actually.

It's an extreme example, but the Tesla Roadster can go about 244 miles on a single charge using modern lithium-ion battery technology. Older electric vehicles like the EV-1 never had access to lithium-ion technology; it didn't exist back then. While it takes roughly 3 hours for a Tesla to fully recharge, in practice we're most likely talking about recharging a battery system that is still partially full, so it likely won't take the full 3 hours unless you run it completely down.

As far as using electric vehicles for interstate travel, the time to charge issue will likely be a problem with us for a while to come. It's difficult to imagine recharging a full bank of batteries entirely in 15 minutes, not without expensive investments in charging stations and the invention of new technologies to facilitate such speed.

8. We don't need fast charging.

We need banks of batteries that are easy to remove and replace. You go to the equivalent of a filling station, where they have a bunch of fully charged batteries. You pay them $20 to replace your spent batteries with fully charged ones. Batteries out, batteries in, and you're on your way. Your old batteries go to someone else when they're through charging.

2. Incremental on practical ones with toxins remaining an issue

The gee whiz stuff seems to come and go between the hype cycles.

5. It will be interesting to see what happens

as carbon nanotube battery technology is perfected and put into production. So far, it promises lighter and more efficient batteries with a shorter turnaround on recharging. We'll see.

6. Soon we may all be driving lemons.

Lemons are used to make batteries in science class.

... Uh, remember?...

Ummm......




Never mind.

7. Perhaps this one day soon..... I hope.

Today’s growing need for energy storage as related to renewables, electric/hybrid vehicles, consumer products, and government applications drives the requirement for a radical change in battery design and production.

In order to achieve such critical requirements in lithium-ion battery performance, Prieto Battery has designed a revolutionary battery architecture intended to address the slow diffusion of lithium-ions (Li+) into and between the anode and cathode.

The conventional battery surface is two-dimensional which limits the direction and speed at which energy can flow. The result is a battery that takes a long time to charge, loses energy quickly, and needs to be replaced often.

The unique 3D architecture, integrates nanowire or copper foam substrate, both of which will have higher power and energy densities than any traditional lithium-ion battery available.
