Nissan developing smaller, lighter car batteries for hybrids and electrics

As demand for green vehicles grows, automakers are racing to develop viable lithium ion batteries, which are common in gadgets such as laptops and cell phones but have yet to be fully adapted to the more rigorous demands of a car engine.

"We continue on the lithium ion battery. We think for us it’s a competitive advantage," he told reporters during a press conference in Bangkok. "We have a lot of technology is this area, and we think this is going to be very helpful, not only for hybrids but also for electric cars."
While consumer interest has surged in gas-and-electric hybrid cars due to higher fuel prices and global warming, the Brazilian-born Ghosn said Nissan was serious about going one step further and introducing vehicles powered only by electricity.
"If you have an efficient battery for a hybrid, why not go all the way and go for electric cars?" he asked. "It has zero emissions of anything."
