Abstract
The present disclosure provides supercapacitors that may avoid the shortcomings of current energy storage technology. Provided herein are supercapacitor devices, and methods of fabrication thereof comprising the manufacture or synthesis of an active material on a current collector and/or the manufacture of supercapacitor electrodes to form planar and stacked arrays of supercapacitor electrodes and devices. Prototype supercapacitors disclosed herein may exhibit improved performance compared to commercial supercapacitors. Additionally, the present disclosure provides a simple, yet versatile technique for the fabrication of supercapacitors through masking and etching.
