Electrochemical Capacitors for Energy Management

TL;DR: A highly flexible solid-state supercapacitor was fabricated through a simple flame synthesis method and electrochemical deposition process based on a carbon nanoparticles/MnO(2) nanorods hybrid structure using polyvinyl alcohol/H(3)PO(4) electrolyte to highlight the path for its enormous potential in energy management.

TL;DR: In this article, layer-by-layer techniques are used to assemble an electrode that consists of additive-free, densely packed and functionalized multi-walled carbon nanotubes, which can store lithium up to a reversible gravimetric capacity of approximately 200 mA h g(-1) while also delivering 100 kW kg(electrode) of power and providing lifetimes in excess of thousands of cycles.
