MIT develops New Battery Technology - Important Implications

The link below is a short, but very interesting article about a new battery charging technology being developed at MIT.  The technology allows lithium-ion batteries to be charged 100 times faster than is now possible.  A cellphone battery with the new technology might be charged in only 10 seconds.  Larger batteries could be charged in 5 minutes instead of 8 hours.

If this technology works, it will have a huge impact on electric cars and trucks.  Lithium batteries are lighter, and if they can be charged in 5 minutes, it then becomes possible to use electric cars/trucks for virtually everything, as recharging the batteries could be done at filling stations in only 5 minutes, not much longer than it takes to fill up the tank with gas.

This doesn't solve peak oil, but it would make a lot of things possible (using batteries) that are not possible today.  It would make 'electricity' the common denominator, as any/all energy sources can be used to create electricity.  This technology could hasten the switch from petroleum-based transportation to electricity-based transportation.  The CC talks about how there are unique qualities of oil that no other alternative energy has - i.e., you can put 20 gallons in a tank and drive 500 miles.  Light, efficient, super-fast-charging batteries could do this, and the electricity could come from ANY source.

Re: MIT develops New Battery Technology - Important ...

Its an interesting technology, but have you also heard how much power is used to juice up the batteries?

 

From the comments section "even a mobile battery with a capacity of ~3WH capacity is going to
require on the order of 200amps to recharge it in 10secs. Uhh, that
means a very thick cable, a hefty connector with thick pins and control
logic which supports such high currents, so not very practical. For
automotive use one also has to consider the other problems with Li-Ion
batteries, such as temperature limits for operation & charging,
beyond which there is permanent damage.
"

A few questions I have are:

1. Will the electricity, to power the batteries, require more or the same amount of fuel to generate it?

2. On avg. how long do these batteries last? 

3. What are the environmental impacts of discarding old/outdated batteries (does this impact outweigh the damage caused by petroleum powered vehicles)?

4.  Will the recycling efforts, in combination with the manufacturing of new batteries, negate the benefits of the batteries themselves?

I guess what I'm trying to say is:

If the benefits of producing and dumping of these batteries do not out outweigh the detriments of the alternative (oil), by a fair margin, then it doesn't seem to be much progress.  If, on the other hand, we're glossing over these details because of our depletion of oil, then that's not good either. 

I was just wondering if these calculations have been made, yet, by any focus groups??
