An All-Solid-State Flexible Micro-supercapacitor on a Chip

A facile strategy is reported for design and preparation of flexible micro‐supercapacitors on a chip based on patterned electrodes of conducting polyaniline nanowire arrays. The interdigital microelectrode is produced by combining microfabrication technology and an in‐situ chemical polymerization approach. The assembled flexible micro‐supercapacitor showed superior volumetric capacitance, fast rate capability and reduced leakage current using H2SO4‐ polyvinyl alcohol gel electrolytes.
