Electric car batteries with 500-mile range on the way


battery 500 miles

The project is progressing with its goal of boosting the range of rechargeable batteries for all-electric cars to 500 miles.

The Battery 500 Project recently held its kickoff meeting at IBM’s Almaden Laboratory in San Jose, Calif., where leading scientists, engineers and other experts brainstormed about how to perfect the power source for all-electric automobiles. (See the video.)

As a part of IBM’s 2-year-old Big Green Innovations program, the Battery 500 Project aims to boost the range of rechargeable batteries for all-electric cars from less than 100 miles today to as far as 500 miles. The consortium’s efforts are being led by the Almaden Lab in collaboration with several U.S. universities and the Department of Energy’s national labs.

“Batteries technology has improved, but is still far inferior to gasoline in terms of how much energy they hold,” said Spike Narayan, a key IBM researcher. “The energy density—which is the amount of energy a lithium-ion battery stores per unit weight—is really not enough to produce a family-sized sedan with a 300- to 500-mile range.”

    Hope electric car batteries will improve more in time. It would help out on lowering fuel-run cars.
