Lithium-ion batteries
Batteries Made from World’s Thinnest Material Could Power Tomorrow’s Electric Cars
Engineering researchers at Rensselaer Polytechnic Institute made a sheet of paper from the world's thinnest material, graphene, and then zapped the paper with a laser or camera flash to blemish it with countless cracks, pores, and other imperfections. The result is a graphene anode material that can be charged or discharged 10 times faster than conventional graphite anodes used in today's lithium (Li)-ion batteries.
Lithium-Air Battery Breakthrough Gives Hopes to EV Industry
Lithium-air battery technology is a promising solution to make the range of electric vehicles comparable to gasoline-powered vehicles. It has the potential to store ten times more energy than the best lithium-ion battery available in the market nowadays. However, no stable battery configuration had been designed until now.

Cost of EV vs Gas engines
Electric Cars--How Much Does It Cost per Charge?
When you compare battery to gasoline power, electricity wins hands down. A 2007 study by the non-profit Electric Power Research Institute (EPRI) calculated that powering a plug-in hybrid electric vehicle (PHEV) would cost the equivalent of roughly 75 cents per gallon of gasoline—a price not seen at the pump for 30 years.
The calculation was made using an average cost of electricity of 8.5 cents per kilowatt hour and the estimated distance the car would travel on one charge, versus a car that gets 25 miles per gallon and is powered by $3 per gallon gasoline. Change any of those variables and the relative costs change. For example, substituting a car that gets 50 miles per gallon doubles the comparative electrical cost (though it still works out much cheaper than gasoline). On the other hand, in some areas where wind or hydropower is wasted at night—just when the PHEV would be charging—the utility might drop the kilowatt hour cost to two to three cents, making the charge much less costly.
