Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with specific embodiments.

[0026] figure 1 It is an electric double layer capacitor, including a container 7 and two sets of electrolytic cells, each set of electrolytic cells includes a positively polarized electrode 1, a separator 2, a positive electrode 3, a separator 2, an electrolyte 5, a separator 2, and a negative electrode arranged in sequence. The electrode 4, the separator 2, and the negative polarized electrode 6; the distances between the polarized electrodes, the separator, the electrodes, and the electrolyte are all 6 microns. The outside of the container is welded with a power supply terminal, which is welded with each electrode inside, and its top view is as follows: figure 2 shown.

[0027] The positive and negative electrodes in this embodiment are a mixture of graphite and metal fibers containing thorium, tantalum, nickel, and copper; the electrolyte is a polyaniline a...

Abstract

The invention discloses a double charge layer capacitor and a preparation process thereof. The double charge layer capacitor comprises a polarized electrode positioned in a container, positive and negative electrodes, isolating membranes and electrolyte, wherein the electrolyte is positioned between the positive and negative electrodes; the polarized electrode is positioned on the outer sides of the positive and negative electrodes; and the isolating membranes are arranged among the polarized electrode, the positive and negative electrodes and the electrolyte. The capacitor has a capacitor structure of double charge layers by adopting a high-density overlapping process, and achieves high-capacity effect under the same volume. Compared with a common energy storage capacitor, the double charge layer capacitor has small volume and high energy storage capacity, and can be widely applied to energy storage of photovoltaic products and in other fields which need high-capacity energy storage.

Description

technical field [0001] The invention relates to a capacitor, in particular to an electric double-layer capacitor used in fields requiring large energy storage capacity. Background technique [0002] With the development of industry, fossil energy such as oil and natural gas can only be exploited for another 40 years. Human beings must find renewable alternative energy as soon as possible, such as solar energy, wind energy and other green new energy, in order to achieve sustainable development. Now many cities have begun to use electric locomotives, light rail locomotives, and battery cars as public transportation vehicles. These vehicles do not burn gasoline and have no pollution. However, because the batteries they use are chemical batteries, their discharge efficiency and cycle life are low, and Improper disposal of waste batteries can lead to lead pollution. "Energy storage capacitor" is a new type of green energy used in this century. It has the characteristics of fast ...
