A couple a years ago Northwestern University announced it had invented a new design on the lithium ion battery that due to eternal engineering it would get 10 times the range and recharge 10 times faster than today lithium ion batteries. If reports were accurate, recharging a Model-S would take about 10 minutes and would give the Model-S a 2,300 mile range, more than enough battery power to get from Chicago to Los Angeles without needing to recharge the battey. It also blows away the the range of gasoline cars.
The technology could be seen in the marketplace in the next three to five years, the researchers said.
A paper describing the research is published by the journal Advanced Energy Materials.
“We have found a way to extend a new lithium-ion battery’s charge life by 10 times,” said Harold H. Kung, lead author of the paper. “Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium-ion batteries on the market today.”

What I'm not sure about is whether it will need 10 times as much electricity to completely charge, which would still be perfectly fine or the same amount of electricity as today's lithium-ion batteries, which will mean "fuel costs" gets down to the gas equivalent of pennies per gallon seen in a slightly higher electric bill as opposed to between $3 and $4 dollars per gallon.
