Estimation of Supercapacitor Energy Storage Based on Fractional Differential Equations

In this paper, new results on using only voltage measurements on supercapacitor terminals for estimation of accumulated energy are presented. For this purpose, a study based on application of fractional-order models of supercapacitor charging/discharging circuits is undertaken. Parameter estimates of the models are then used to assess the amount of the energy accumulated in supercapacitor. The ...

Integrated photoelectrochemical energy storage: solar hydrogen generation and supercapacitor

Current solar energy harvest and storage are so far realized by independent technologies (such as solar cell and batteries), by which only a fraction of solar energy is utilized. It is highly desirable to improve the utilization efficiency of solar energy. Here, we construct an integrated photoelectrochemical device with simultaneous supercapacitor and hydrogen evolution functions based on TiO(...

The Composite Supercapacitor

Inspired by the design of composite materials, a novel composite supercapacitor is proposed comprising an integrated cell with high powerand high energy-related electrode materials so that the composite electrochemical double layer capacitor (EDLC) is the equivalent circuit of a high power EDLC of power P1 and energy E1 and a high energy EDLC of power P2 and energy E2 connected in parallel. A m...
