Investor's Business Daily - Nanotechnology may soon improve battery life, according to Stanford researchers, who demonstrated how it can make lithium batteries -- popularly used to power iPods, laptops and cell phones -- last 10 times longer. The new method using silicon nanowires could yield an option for electric cars or solar panels to store more electricity. The researchers said the lab technique could be scaled up for mass production and are considering forming a company or agreement with a battery manufacturer.
