    摘要： There is disclosed a method and a system for a versatile in-situ approach to design the nanostructured transition metal selenide (TMS) materials for the high-energy solid-state hybrid supercapacitors (HSCs). Initially, the rose-nanopetals like NiSe@Cu2Se (NiCuSe) cathode and FeSe nanoparticles anode are directly anchored on 3D highly conducting Cu foam via purposefully in-situ conversion reactions. The different potential windows of the NiCuSe and FeSe in aqueous electrolytes associated with the excellent electrical conductivity and redox activity results in the superior electrochemical features for the half cell with maximum specific capacity of 534.2 mA h g−1 for NiCuSe and 573.8 mA h g−1 for FeSe at current density of 1 A g−1, respectively. The solid-state HSC cell with NiCuSe cathode and FeSe anode delivers a highest specific energy of 87.6 Wh kg−1 and excellent cycle lifetime with capacity retention of 91.3% over 10,000 cycles.

    摘要： The present invention provides an on-chip all-solid-state supercapacitor, which includes a first electrode and a second electrode, and both the first electrode and the second electrode include a substrate, a laminated structure, a conductive thin film layer and a solid electrolyte. The laminated structure is disposed on a surface of the substrate and is provided with at least one deep trench structure; an inner surface of the deep trench structure is provided with a sacrificial layer trench, which increases the electrode area of the on-chip all-solid-state supercapacitor, and further increases the capacitance density and energy density; the conductive thin film layer covers the inner surface of the deep trench structure, an inner surface of the sacrificial layer trench, the surface of the substrate exposed in the deep trench structure and a surface of the laminated structure facing away from the substrate; the solid electrolyte is filled inside the sacrificial layer trench and the deep trench structure covered by the conductive thin film layer; the solid electrolyte also covers a surface of the conductive thin film layer facing away from the substrate, and the solid electrolyte of the first electrode and the solid electrolyte of the second electrode are bonded together. The present invention also provides a preparation method of an on-chip all-solid-state supercapacitor.

    摘要： A composite with high energy storage capacity for use in energy storage devices includes graphene and mesoporous graphitic carbon nitride (mc@g-C3N4). The graphitic carbon nitride is coated on mesoporous carbon (mc@g-C3N4) at a concentration ranging from 3% to 33%. The graphitic carbon nitride is obtained from condensation of mesoporous carbon and urea or a precursor thereof. Electrodes may be prepared from the composite. High energy high power storage devices such as the Electric Double Layer Capacitor (EDLC) may be fabricated with these electrodes.

    摘要： A capacitor includes a first metal layer disposed on a wafer or substrate, a first polarized dielectric layer above the first metal layer and comprising a plurality of electrets formed by aligning molecular dipoles throughout a three-dimensional surface area of a polarizable dielectric material during polarization by applying a momentary electric field of positive or negative polarity, a second metal layer disposed on the first polarized dielectric layer to electrically isolate the first polarized dielectric layer, and a second polarized dielectric layer above the second metal layer, the second polarized dielectric layer comprising a plurality of electrets formed by aligning molecular dipoles throughout a three-dimensional surface area of a polarizable dielectric material during polarization by applying a second momentary electric field of opposing polarity. A plurality of alternating polarized dielectric layers and metal layers may be arranged in series to form a stack, with an internal passivation layer disposed between each stack.
