Micro-Supercapacitors Could Boost Lifetime of Portable Devices

Micro-supercapacitors could enable future geeks to go longer without recharging their smartphones or computers. Researchers have developed a way to build the energy-storing supercapacitors by using microfabrication methods similar to those which create microchips for electronic devices, according to ScienceDaily. Gogotsi worked with John Chmiola, a chemist at the Lawrence Berkeley National Laboratory. They etched electrodes made of monolithic carbon film into a conducting substrate of titanium carbide, and created micro-supercapacitors with an energy storage density at least twice as much as existing supercapacitors.
