Achieving a supercapacitor through molecular coating for increased capacity, lifetime durability, and cost-effectiveness

"carbon nanotubes increase surface area, capacity, but large-scale production not cost-effective... 2.4X increased capacity to 907 F/gAC by sprinkling iron azaphthalocyanine onto activated carbon, enabling molecular level adsorbtion, utilizing redox capabilities... 20K charge-discharge cycles even in high-load regions of 20 A/gAC, powering LEDs... same capacitor can be reused many more times... significantly less toxic than batteries... increase capacity to level of CNT supercapacitors using cheaper materials"
