URBANA, Ill. – Engineers claimed Friday that they discovered a way to significantly prolong battery life, meaning that cell phones and laptops could run for months without having to be recharged.
The University of Illinois researchers said they developed a form of ultra-low-power digital memory that could extend battery life by up to 100 times, by replacing metal wires in the devices' memories, which use up most of their battery power, with so-called nanotubes -- carbon tubes 10,000 times smaller than a human hair.
