Abstract

Nanosupercapacitors, also called electrochemical supercapacitors or nanocapacitors, thus emerge as promising fuel sources with astonishingly fast charge release rates. Incredibly fast charging occurs. Created to improve power execution (high-speed capability), they still depend on similar inherent breakpoints. About the electrical characteristics and the manufacturing process of a nanocapacitor structure using (metalinsulator-carbon-metal nanotube layers). This structure shows high capacitance and the possibility of extremely high integration density due to the unique structure of the nanotubes. Nanoscale patterns and a high aspect ratio are obtained by electron beam lithography to make these vertical nanostructures. This structure can be used to replace capacitors that use a silicon pillar structure in dynamic random access memory (DRAM) or as a nanoscale capacitor for various nanoelectronic devices. .To build nano supercapacitors, high voltage and high energy density developed multilayer nanostructure technologies to make an improvement in capacitor performance. Controlled sputtering techniques can deposit ultra-smooth submicron layers of dielectric and conductive materials. Using this technology, high voltage nanosupercapacitors with an order of magnitude improvement in energy density may be achievable.. Dielectrics and new materials that are well understood for use with this technology. Nano supercapacitors developed with multi-layer nanostructure technology are inherently solid and show excellent mechanical and thermal properties. >Dielectric materials and exchanges design with more layers. Nanostructure multilayer capacitors will be developed and specified.
