Abstract:

Microsupercapacitors (MSCs) are microfabricated energy storage devices that utilize the rapid adsorption and desorption of ions at the electrode/electrolyte interface to store charge or electrical energy.  To enable a microscale size, potential for on-chip integration with other electronics, and more rapid charge/discharge rates, MSCs are microfabricated with planar interdigital electrodes which differs from the conventional stacked electrode architecture of typical supercapacitors. Compared to thin film batteries, MSCs have advantages such as higher power density and extended cycle life, but the energy density is lacking. As a result, these miniaturized devices are attractive for use as energy storage components for self-powering electronics.
