Nanocarbonsfor Supercapacitors
2012Supercapacitors (or electrochemical capacitors) are electrochemical energy storage devices having higher energy density than dielectric capacitors and higher power density than batteries. Actually, they are capable of delivering large amounts of energy in a very short time. These devices rely mainly on the characteristics of the electrical double layer

ECS Meeting Abstracts, 2016
In our studies, gate electrodes were placed in mid-position between the anode and the cathode of electrolytic capacitors. Ionic currents were made to flow through these gate electrodes. The gate was an electronic p-n junction and consisted of p-type and n-type functionalized carbon nanotubes (CNT).

Smart, Stretchable Supercapacitors
Advanced Materials, 2014Smart supercapacitors are developed by depositing conducting polymers onto aligned carbon-nanotube sheets. These supercapacitors rapidly and reversibly demonstrate color changes in response to a variation in the level of stored energy and the chromatic transitions can be directly observed by the naked eye.

System for characterization of supercapacitors
2016 International Conference on Electronics and Information Technology (EIT), 2016The hardware and software system, based on LabVIEW package, for electrical investigations of supercapacitors was developed. The system provides standard testing (cyclic voltammetry, constant current charge and discharge, electrochemical impedance spectroscopy, etc.) of supercapacitors in the temperature range of 30 to 100° C and under pressure up to 3 ...
