Abstract

The invention discloses a physical battery. The physical battery comprises aluminum films as upper and lower electrode layers and titanium dioxide as a middle dielectric layer, wherein titanium oxidelayers are further arranged between the electrode layers and the dielectric layer; the aluminum films have the thickness of 8 microns, and the titanium dioxide is flaky titanium dioxide having the diameter of 50-500 microns and the thickness of 1-20 microns and having a complete structure. The invention further discloses a production method of the physical battery. The production method comprisesthe following steps: 1), preparing the flaky titanium dioxide into a slurry; 2), cleaning the surface of the aluminum film, and flatly laying the aluminum film as a bottom electrode; 3), casting the titanium dioxide slurry on the surface of the aluminum film; 4), drying at 80-95 DEG C, and then annealing the dried film at 200-550 DEG C; 5), covering the film with the aluminum film with the thickness of 8 microns as an upper electrode; 6), gluing in vacuum; 7), curing glue by using ultraviolet. The production method is suitable for casting forming, mass production is easy, and the energy density of the physical battery produced according to the production method can reach 330J / cc.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a physical battery based on sheet-type titanium dioxide and a manufacturing method thereof. Background technique [0002] There are many ways of energy storage, such as flywheel, storage battery, supercapacitor, superconducting energy storage technology, etc., have been widely researched and utilized. Among them, the storage of electric energy is an important aspect of this application research, and it is also an important issue that is difficult to solve at present. For the storage of electrical energy, the chemical energy storage method is widely used, that is, the energy is converted into chemical energy for storage, and when used, the chemical energy is converted into electrical energy for release and then utilized. With the rapid development of modern technology, the storage / release of electric energy plays an increasingly important role. [0003] Batteries a...

Problems solved by technology

[0006] However, due to the presence of the electrolyte solution, the use environment of the capacitor is subject to certain restrictions.

When the ambient temperature is high, the electrolyte solution changes accordingly, which may cause safety hazards such as capacitor bursting; and at high temperature, the ion migration speed in the electrolyte solution increases, the conductivity of the solution increases, and the loss of the capacitor increases, making the supercapacitor temperature continues to rise

In addition, the product of the electrolysis reaction may be a gas component, and the continuously generated gas will eventually destroy the supercapacitor
