Georgia Tech researchers have developed a method for making energy storage devices at the micro-scale. The device consists of an etched silicon cavity filled with a metallic conductive layer and an array of carbon nanotubes to form an enclosed electrochemical double layer capacitor when filled with electrolyte.
- Micro-scale – Chip size supercapacitors
- High Energy – High energy storage at a small-scale
- Fully Integrated – Carbon nanotube components are not physically mounted on substrate
- Miniaturized energy storage
- On-chip sources
Electronics have made a shift from micro to nano-scale sized devices within the past decade. With the increase in miniaturization, electrical components, such as resistors, batteries, and capacitors have been modified and redeveloped to fit the physical and mechanical characteristics of nano-scale electrical environments. The increased need for devices with high-energy storage and fast energy discharge capabilities has increased the demand for high-energy capacitors.
