CDL Supercapacitor: Powering the Future of Energy Storage
Subcategory (under Clean Energy): Cross Cutting
Technology Readiness Level (TRL): TRL 4 - Early prototype
Technology Outline (Process Description)
The ‘CDL Supercapacitor’ technology employs a solid-state flexible asymmetric supercapacitor (SS-FASC) design to revolutionize energy storage. The process begins with the fabrication of MnO2 and CuS thin film electrodes using advanced materials and cutting-edge engineering techniques. A PVA-Na2SO4 polymer gel electrolyte is integrated to ensure safe and durable operation without the need for liquid electrolytes.
The prototype adopts a stacked configuration of pouch cells, each measuring 5 cm x 5 cm x 0.5 cm. These cells are interconnected in series and parallel combinations to achieve the desired energy storage capacity and power output. Customization is possible with multiple stack configurations to suit specific application requirements.
To validate performance, extensive testing is conducted, employing cyclic voltammetry (CV), galvanostatic charge- discharge (GCD), and electrochemical impedance spectroscopy (EIS). The data obtained helps evaluate specific capacitance, energy density, power density, and shelf-life performance.
The CDL Supercapacitor technology represents a significant leap in energy storage, promising flexible, efficient, and sustainable power solutions for diverse industries and applications.
