Nanom’s nanotech makes more efficient batteries that last at least 9 times longer.

Nanom is unveiling a patented technology that uses nanoparticles to make batteries that are far more efficient than the ubiquitous lithium-ion version used today.

If it works, the technology could revolutionize batteries used in everything from electric cars to laptops and smartphones. Nanom claims its batteries last 9 times longer than the nickel-iron batteries Thomas Edison invented and more than than 9 times longer than lithium-ion batteries. They also weigh 5 times less and improve energy density, recharge rates, and battery disposal.
