Embodiment Construction

[0034] figure 1 The flow chart of the manufacturing method of the large-capacity capacitor provided for the embodiment of the present invention, as figure 1 As shown, the method includes:

[0035] Step 101, the metal salt or metal oxide is sequentially processed through sol, gel, aging and solvent replacement processes to obtain a metal oxide gel;

[0036] The metal salt in this embodiment, for example, can be copper chloride, copper sulfate, etc., copper chloride or copper sulfate is catalyzed by water and organic solvents such as ethanol, n-hexane or n-heptane, according to Add a certain proportion of polyacrylic acid to mix and stir evenly, then add propylene oxide and stir evenly, let stand for a while and wait for gelation. For example, dissolve copper chloride in ethanol, such as copper chloride in 10% weight concentration ethanol solution, add 30% weight deionized water and mix evenly, then add 15% polyacrylic acid and stir for 0.5-1 Hours, after stirring evenly, slo...

Abstract

Provided are a manufacturing method of a high-capacity capacitor, capacitor battery and battery pack. The method comprises: performing solation, gelling, aging and solvent exchange, and drying processes on a metal salt or metal oxide to obtain a metal oxide aerogel; performing oxygen insulation and heating on the metal oxide aerogel, and jetting a reduction material to obtain metal nano-particles; depositing and pressing the metal nano-particles onto a metal substrate, and heating the metal substrate to a preset temperature to obtain a metal cluster polarized plate having a preset specific surface area, the preset temperature being lower than a melting point of the metal; cutting the metal cluster polarized plate to obtain two capacitor polarized plates; and filling insulating material between the two capacitor polarized plates, pressing the insulating material, mounting an electrode and encapsulating to obtain a high-capacity capacitor. Based on the high-capacity capacitor, a high-capacity capacitor battery can be manufactured in combination with an additional discharge-on-demand control device, thus achieving discharge according to demand.

Description

technical field [0001] The invention belongs to the technical field of electronic device manufacturing, and in particular relates to a method for manufacturing a large-capacity capacitor, a capacitor battery, and a battery assembly. Background technique [0002] Capacitors are one of the most commonly used electronic devices. With the advancement of electronic technology and energy technology, the demand for high-performance large-capacity capacitors is increasing. For example, large-capacity capacitor batteries, which have become one of the key directions of battery research, are based on bulk capacitor. At present, the large-capacity capacitor batteries that have been studied are all capacitor batteries filled with electrolyte, which have the disadvantages of long charging time, complex structure, and low withstand voltage. [0003] According to the calculation formula of capacitor capacitance: C=Q / U, where Q is the amount of charge (K) stored between the plates of the ca...
