Will a micro-supercapacitor power your wearware and implants. By etching electrodes made of monolithic carbon film into a conducting substrate of titanium carbide, John Chmiola, a chemist with the Lawrence Berkeley National Laboratory was able to create micro-supercapacitors featuring an energy storage density that was at least double that of the best supercapacitors now available. When used in combination with microbatteries, the power densities and rapid-fire cycle times of these micro-supercapacitors should substantially boost the performance and longevity of portable electric energy storage devices.
