    Flexible binder free functionalized carbon nanotube electrodes for ultracapacitor
    (SPIE spie@spie.org, 2014) Badekai Ramachandra, B.R.; Aravinda, L.S.; Bhat, K.U.
    The Flexible supercapacitor electrode material was prepared by simple spray coating technique. This will provide a greener alternative for the fabrication of binder free composite electrode for supercapacitor applications. A symmetric double layer super capacitor stack was fabricated by using flexible electrodes. The investigation of the capacitance property of the fabricated super capacitor stack was investigated using cyclic voltammetry, chronopotentiometry and electrical impedance spectroscopy studies. The flexible electrode material shows a specific capacitance of 50 Fg-1 with good cyclibility. © 2014 SPIE.

    Sustainable Off-Grid Electricity Generation System for Low Power Lighting in Remote Locations
    (Institute of Electrical and Electronics Engineers Inc., 2020) Shenoy, B.B.; Mitra, J.; Shripathi Acharya, U.; Laxminidhi, T.
    This paper proposes an environmental friendly and sustainable approach to generate electricity for small lighting applications in rural and remote locations. In the proposed system, human muscle energy, abundantly available in rural and remote locations, has been converted into electrical energy to be stored in an alternative energy storage device, e.g. a supercapacitor. The usual bicycle with a minor modification is plugged to a charging platform. The charging platform has a power processing circuit and a Permanent Magnet Direct Current generator. The system has the ability to power up a 1 W white LED lamp for a duration of approximately 60 minutes, when the bicycle is pedaled for 4 minutes. The proposed system is not only eco-friendly, but also effectively caters to the challenges posed by seasonal variations and locational disadvantages and is targeted specifically for locations which are not having access to the power grid. © 2020 IEEE.

    Analysis of Leakage Current Mechanism in Supercapacitor with Experimental Approach
    (Institute of Electrical and Electronics Engineers Inc., 2022) Bairwa, B.; Pareek, K.; Sarvagya, M.; Yaragatti, U.R.
    In this paper, we evaluated the leakage current of super capacitor during self-discharge. A three branch electrical equivalent circuit model (ECM) is constructed to estimate voltage response and leakage current of commercially available 2.7 V 350F (BCAP350) double-layer capacitor (DLC). Experimental work carried out with two constant current charging segments 0.25 ampere, and 0.5 amperes. Simulated data shows good agreement with experimental results obtained at electro-chemical workstation CH760e with RMSE and MAE error up to 0.0633, 0.05715, and 0.0759, 0.04173 for 0.25 ampere and 0.5 amperes charging current, respectively. The results confirm that the ECM model is capable to simulate the complex terminal behavior of the super capacitor and provides the means to study its application as an energy storage device. © 2022 IEEE.
