Electric Cars it s all about the battery

I own an electric car (on my second one now) that I use for around town. It s fine for short jaunts, which is the majority of driving. However the limiting factor is of course the battery and the range associated with it.

While I can get about 40 miles of city driving, I could probably double that with a lighter, more efficient battery. While I know some people pooh-pooh electric cars, I think mine is rather fun. With gas prices headed toward $5 a gallon, I ll have even more fun.

My electric car, shown above a bit like a smart car , but slightly larger. My first was little more than a glorified golf cart. This one is full featured.

New high-performance lithium-ion battery top candidate for electric cars

Scientists are reporting development of an advanced lithium-ion battery that is ideal for powering the electric vehicles now making their way into dealer showrooms. The new battery can store large amounts of energy in a small space and has a high rate capacity, meaning it can provide current even in extreme temperatures. A report on this innovation appears in ACS Journal of the American Chemical Society.

Bruno Scrosati, Yang-Kook Sun, and colleagues point out that consumers have a great desire for electric vehicles, given the shortage and expense of petroleum. But a typical hybrid car can only go short distances on electricity alone, and they hold less charge in very hot or very cold temperatures. With the government push to have one million electric cars on U.S. roads by 2015, the pressure to solve these problems is high.

BAIC E150 EV Electric Cars

To make electric vehicles a more realistic alternative to gas-powered automobiles, the researchers realized that an improved battery was needed.

The scientists developed a high-capacity, nanostructured, tin-carbon anode, or positive electrode, and a high-voltage, lithium-ion cathode, the negative electrode. When the two parts are put together, the result is a high-performance battery with a high energy density and rate capacity. On the basis of the performance demonstrated here, this battery is a top candidate for powering sustainable vehicles, the researchers say.

The authors acknowledge funding from WCU (World Class University) program through the Korea Science and Engineering Foundation.
