136How more EV sales in America is hurting China's environment

One of the bigger knocks against hybrid and electric vehicles is that while they don't directly produce much in the way of harmful emissions (if they make any at all), the process of building their electric motors and batteries can be very, very bad for the environment. Take graphite, for example. It's an essential ingredient in lithium-ion battery packs, like the one shown above in the back of a Toyota Prius Plug-In. According to Bloomberg, the average hybrid car uses about 22 pounds of graphit

35Nissan testing new, heat-resistant batteries for Leaf

As Nissan Leaf sales continue to heat up, the maker of the electric vehicle wants to cool concerns over hot-climate battery issues by making chemical adjustments to battery packs, Green Car Reports says. Nissan executives met with about 10 Leaf owners in Phoenix last week and said the company is approaching a solution that will better allow Leaf lithium-ion batteries to withstand extensive heat without losing capacity faster than Leafs that live in cold-weather climates.

54Battery costs will fall to $250/kilowatt hour by 2015

Our most burning question – aside from how many licks it takes to get to the center of at Tootsie Pop – is, how much does a battery-electric vehicle's battery really cost? One analyst says that the price tag will be at about $250 per kilowatt hour by 2015, which spells good news for the EV industry.

12New Kia Ray is Korea's first production EV

Kia has unveiled the automaker's very first production electric vehicle. The Kia Ray EV will offer buyers a range of around 86 miles depending on driving conditions and will include a fast-charge option that should top off the cells in around 25 minutes. Otherwise, expect the 16.4-kWh lithium-ion battery pack to take around six hours to charge on a 220-volt circuit. A 50-kW electric motor provides power to the front wheels, which is good enough to get the EV to 62 miles per hour in 15.9 seconds.
