Supercapacitor is a kind of effective energy storage device with merits such as high power density, long cycling life and so on, but their application is limited nowadays compared to the application of batteries. One important restriction is because of the serious self-discharge in supercapacitors, and how to conquer the self-discharge problem is an important issue. In this article we propose an effective way to reduce self-discharge of the supercapacitor by carefully designing of activated carbon (ACs) electrodes and water-in salt electrolyte. The electrochemical characterization shows that our supercapacitor can have the ability to reduce self-discharge.

Graphite Composites

Herein we present a study on polymer-derived silicon oxycarbide (SiOC)/graphite composites for a potential application as an electrode in high power energy storage devices, such as Lithium-Ion Capacitor (LIC). The composites were processed using high power ultrasound-assisted sol-gel synthesis followed by pyrolysis. The intensive sonication enhances gelation and drying process, improving the homogenous distribution of the graphitic flakes in the preceramic blends. The physicochemical investigation of SiOC/graphite composites using X-ray diffraction, 29Si solid state NMR and Raman spectroscopy indicated no reaction occurring between the components. The electrochemical measurements revealed enhanced capacity (by up to 63%) at high current rates (1.86 A g−1) recorded for SiOC/graphite composite compared to the pure components. Moreover, the addition of graphite to the SiOC matrix decreased the value of delithiation potential, which is a desirable feature for anodes in LIC.
