Abstract

The invention discloses a high-capacity energy storage capacitor which is formed by connecting a first dielectric film and a second dielectric film in parallel. The upper surfaces and the lower surfaces of the two dielectric films are respectively provided with an electrode layer, and the outer surface of each electrode layer is provided with a base layer; the first dielectric film is prepared bycompounding an organic material with dielectric constant of 3 with Ba0.9Ca0.1Zr0.06Ti0.94O3; and the second dielectric film is prepared by compounding an organic material with dielectric constant of 3 with Ba0.9Ca0.1Zr0.21Ti0.79O3. In the invention, the capacity of the capacitor is improved by improving the dielectric constant of a medium layer of the capacitor.

Description

technical field

[0001] The invention relates to a novel energy storage device, in particular to a large-capacity capacitor that can be used for power storage, and can be widely used in multiple fields such as electric power, energy and civil use. Background technique

[0002] Electric energy is an indispensable and important resource in contemporary society, and the quality of energy storage equipment directly affects the full application of electric equipment. In recent years, with the development and use of portable equipment, uninterruptible power supply systems and electric vehicles, the use of batteries is increasing. Rechargeable batteries, especially lead-acid batteries, are widely used in various industries due to their excellent features such as low price, stable performance, and no memory function. However, the storage battery is restricted by its inherent conditions, and there are problems such as poor cycle life, poor high and low temperature performance, sensit...
