Lithium Ion Batteries - Full charge in a couple of minutes

[Ships_Cat]

Thought some may be interested in this new battery technology just announced by Toshiba to start coming available next year.

Found at http://www.toshiba.co.jp/about/press/2005_03/pr2901.htm.

That will make a difference onboard!But what are the battery suppliers go to say?

Useing nanotech means material and production costs will remain the same, i just wonder what the price will be?

 

[ongolo]

Yes, and where will they be available in Africa, any limitation on supply? Cost? are they looking for agents?

So Lead mines will also close down? Good for the environment. Finally something good in 2005. Now they only have to rmove Bush and Blair.

regards and thanks ongolo

Indeed it is a breakthrough John. There was an article in Scientific American about Li-ion batteries about 2 years ago. Unfortunately they have only produced diddy little ones so far and achieving as much as 100 Amp-hours is currently enormously expensive and impractical as I understand it. They are continuing research however in consortium with others and have a budget which is supported by the Japanese Government with the target of producing a usable battery for electric vehicles by 2010. It is also suggested that there is a NASA funded project trying to beat them to it..... We may have to wait a bit........ Although the one they are working on will be great for computers.

From the website
>>>
2) High Energy Density
Small and light, the new battery offers a high level of storage efficiency. The prototype battery is only 3.8mm thick, 62mm high and 35mm deep and has a capacity of 600mAh.
>>>

So, 600mAh recharges in a minute. Useful for my phone and Airsoft gear but I'd need a lot of these to make up the 290Ah I have on board, which would want 483 minutes to charge, 8 hours is good from all flat though.

My phone battery is already Li ion and I suspect yours is too so I assume the big breakthrough is cost.

Time to invest in rubber production, just imagine all those fan belts snapping under the load of high power alternators.

I agree it sounds interesting for a lot of applications, but the graph shows that they will remain the same cost as current Li-ion batteries. At the moment these are about a fiver for the sized batteries Andrew descrbes below, which would make the equivalent of a 100Ah 12V lead acid cell of the order of eight thousand pounds, if they went into mass production. And that's only if the production cells live up to the hype; remember what they said about nickel metal hydride?

I think I'll stick to lead-acid for now, but once the technology has lived up to its expectations I'll dump the diesel and fit a bunch of these batteries and an electric motor. If I live that long. /forums/images/graemlins/smile.gif They are nearly as expensive as the (similar capacity) methanol fuel cells that we were talking about last month.
