What is needed for battery Applications.

The long recharge times was one of the things that killed the electric cars in the twentieth century. It is a critical factor in commercial applications. "Time is Money" The question asked in the comments about providing a 100KW line needs to be answered YES! With recharge times of less than five minutes, you can begin to handle the energy with "filling stations."

This is what we are looking at for the future of pollution sensitive areas like New York and California. The power-to-weight ratio is not so important, not unimportant just less so.

If you can make an electric car that can run a hundred miles, at speed (call it 85 mph), recharge in around five minutes and can be profitably sold for less than 20% over the cost of gasoline competitors, including the cost of recycling the battery, then you have a commercial product. These are the parameters that have to be met for a working electric Car that is not confined to niche markets.

The politicians that are providing the 20% incentive will also have to live with vastly increasing the numbers of Nuclear power plants (about five times) and upgrading the power grid to support electric transportation. This battery sounds good; there are also the new Ultra Capacitors that could fill the role if they can be brought down in cost by 60%. None of the technology is in place today but understanding the parameters will keep resources from being squandered.

If the battery is truly "fast charge" then your filling station is just a set of magnetic induction coils at traffic lights or along highways in a pull out lane.

If you are stopped at a red light for 30 seconds, you might get a 50% recharge. Billing based on RFID. Of course, it wouldn't charge vehicles on a "bad" or "stolen" list, so they'd eventually go dead.

I am not prepared for that kind of government control over my driving/whereabouts. Thanks though.
