Lithium Metal Polymer Battery powered car
« on: November 06, 2010, 11:43:33 PM »
I'm not really sure where this should go, since it's a battery that has been used in an electric car, but also a forklift, and it has great potential as a storage battery for home power use.

First, a link to the article.... http://sufiy.blogspot.com/2010/10/lithium-metal-polymer-battery-from-dbm.html

Then their YouTube channel... http://www.youtube.com/profile?user=lithiummetalpolymer&annotation_id=annotation_83201&feature=iv

And finally, a news article about it.... http://www.spacedaily.com/reports/German_electric_car_sets_world_record_999.html

After reading the article, my first thought was that someone from the oil industry is going to scoop this up and bury it, pronto.

But it has the backing of the German government, so it might have traction.

If it isn't too good to be true, it is an amazing breakthrough in battery technology. I'd love to have a few for the home power set up!
But somehow I don't think "cheap" is going to be a word used to describe these though.. :-\

Any thoughts from the experts?

I would say that this battery is real, but the price would be fairly high.  Thunderpower just came out with their 65/130 C Lipo packs, so they can discharge in ~55 seconds.    As for the energy density, the new batteries that big manufactures are coming out with have some impressive numbers, so edging the competition like these people did is no surprise.

As for the charging in 6 minutes, that's really, really fast.  That's 10 C, so a 100kwh pack would require 1 Megawatt....  the car would require 220 kw.  I don't see anyone needing to charge their car in 6 minutes.  I remember some students at MIT I think built a car that actually charged in 12 minutes and drove 100+ miles, but they had their own power plant to play with.

As for the oil companies buying the rights, I doubt one company could stop the progress again like the issue in the 1990's with the NIMH cells.  Too many companies have good designs.

The future is coming.

People who want to 'fill up' as fast as with a fossil fuel may want that sort of charge speed: I estimated a normal petrol pump to be the equivalent of ~3MW when filling a car's fuel tank.

I calculate it to about 10-14 MW for a good gas pump (not the slow ones that take 15 mins >:().

Here in Europe we don't need the same bandwidth at our petrol pumps!  B^>

But yes, you may well be right.  The point is that a decent substation on site could supply energy for the 'pumps' without straining too hard in built-up areas with a decent metro grid, though reinforcement would probably be a good idea...

Thanks for the comments guys.

The potential for these up and coming technologies is incredible.

I'll be the first in line to buy a chainsaw with one of those batteries in it!

As for the charging time, in this "gimme now" society, 12 minutes is an eternity. 6 minutes is about average for a regular gas fill up. My old Ford F-250 is on propane with 2 huge tanks and it takes me 20 minutes, once every 2 weeks or so. I think I have adapted well....

Hey HM,

You're practically European now.  Just hold still while I tattoo a communist emblem on your chest and give you some free healthcare!  %-P
