ABSTRACT

Nowadays, flexible electronic components are gaining significant attention in the modern energy storage system. The flexibility of electronics has triggered a tremendous advantage to miniature a micro-sized energy storage cell with very high energy consumption. Flexible electronics leads a sparked revolution in electronics such as smartphone, laptop, electronic skin, flexible display, light-emitting diode (LED), implantable medical devices, etc. Micro-sized energy storage are being paved a great attention due to their various unique properties like ultra-high power density, long cycling lifetime, excellent flexibility, smaller size, high electrochemical performance, and interdigited architecture. In present technological demand micro-sized energy storage devices, i.e., microsupercapacitors (MSCs) have a pronounced potential demand rather than conventional batteries or electrolytic capacitors for various types of energy and power sources. The rapid development on micro-supercapacitor technology have been researched successively through various mode like material evolution, morphology evolution, structural evolution, patterning evolution, growth technique evolution, etc. The materials used for the micro-supercapacitor study are thinned to its micrometer or nanometer scale to exhibit various novel and exceptional physical and electronic properties. Basically, the potentiality of MSCs depends upon the physical, mechanical, and electrochemical properties of the electrode material. Hence, to find out the appropriate electrode materials is a great challenge for the fabrication of flexible and stable MSCs.
