Embodiment 1

[0021] Prepare a layer with an area of ​​10×10cm on the surface of metal aluminum by vacuum evaporation technology 2 , 3,3'-dimethyl-5,5'-di-tert-butyldiphenoquinone with a thickness of 1 μm, and then spin-coat a layer of polyimide with a thickness of 5 μm on the surface of the diphenoquinone layer. Finally, a layer of polyvinylcarbazole polymer (average molecular weight: 19325) with a thickness of 750 nm was spin-coated on the polyimide surface. After drying and solidification, a layer of 100 nm metal aluminum is vacuum-evaporated on the surface of the polymer to obtain the all-solid-state energy storage device of the present invention. Tests show that the all-solid-state energy storage device can be charged within 1.5 minutes, with an energy density of 500Wh / kg and a power density of 8.7kW / kg.

Embodiment 2

[0023] Vacuum evaporation technology is used to sequentially evaporate the area of ​​10×10cm on the glass surface 2 , a thickness of 100nm metal copper, a thickness of 500nm diphenoquinone (3,3'-dimethyl-5,5'-di-tert-butyl diphenoquinone and 3,5-dimethyl-3',5 A mixture of '-di-tert-butyldiphenoquinone, the mass ratio is 1:1), SiO with a thickness of 200nm 2 . Then a layer of poly(p-phenylene vinylene) (average molecular weight 8050) with a thickness of 380 nm was spin-coated on the surface. After drying and curing, a layer of metal copper with a thickness of 100 nm is vacuum evaporated on the surface of the polymer to obtain the all-solid-state energy storage device of the present invention. Tests show that the all-solid-state energy storage device can be charged within 1 minute, with an energy density of 536Wh / kg and a power density of 9.4kW / kg.

Embodiment 3

[0025] Prepare a layer with an area of ​​10×10cm on the surface of metal aluminum by vacuum evaporation technology 2 , 3,3'-dimethyl-5,5'-di-tert-butyldiphenoquinone with a thickness of 2 μm, and then spin-coat a layer of polydimethylsiloxane with a thickness of 5 μm on the surface of the diphenoquinone layer. Finally, a layer of polyvinylcarbazole polymer (average molecular weight: 1930) with a thickness of 1.8 μm was spin-coated on the surface of the polydimethylsiloxane layer. After drying and curing, a layer of metal aluminum with a thickness of 100 nm is vacuum deposited on the surface of the polymer to obtain the all-solid-state energy storage device of the present invention. Tests show that the all-solid-state energy storage device can be charged within 3.5 minutes, with an energy density of 483Wh / kg and a power density of 8.2kW / kg.

Abstract

The invention relates to an all-solid-state power storage device which mainly comprises an electrode, a charge storage material and an insulating material. The charge storage material comprises a positive charge storage material and an electronic storage material which are separated by the insulating material, and a sandwich structure of an electrode / the positive charge storage material / the insulating material / the electronic storage material / an electrode is formed. The positive charge storage material contacts with a positive electrode, and the electronic storage material contacts with a negative electrode. The all-solid-state power storage device is high in energy density and power density, environment-friendly, and high in safety.

Description

field of invention [0001] The invention relates to an all-solid-state energy storage device. Background technique [0002] The energy problem is an unavoidable problem in the development process of countries all over the world. In order to solve the energy bottleneck, all countries have formulated energy technology development strategies to make full use of existing energy and vigorously develop new energy storage equipment. Traditional energy storage materials such as batteries and capacitors have played an important role in the field of energy storage, but the energy density of batteries is high and their power density is low, which is mainly due to the fact that batteries can generate charges and store electrical energy through electrochemical reactions. , therefore, it takes a certain amount of time to charge or discharge the battery, resulting in a low power density. In recent years, research on lithium-ion batteries has been extensive and has entered the stage of com...
