Preparation method of titanium dioxide double-layer thin film electrode

Abstract

The invention provides a manufacturing method for a titanium dioxide double-layer film electrode. The method includes the following steps: (1) adding isopropanol into a titanium tetrabutoxide solution, stirring and adding a salpeter solution; (2) stirring the mixed solution in the step (1), reacting under the heating condition, then adding an emulsifier and additive, and stirring to obtain colloid; and (3) coating the colloid on the surface of a single-layer titanium dioxide film, drying at the constant temperature, increasing the temperature, immersing in dye, and obtaining the titanium dioxide double-layer film electrode after immersion. Compared with the prior art, the titanium dioxide double-layer film electrode obtained through the method is high in compactness and favorable for improving battery efficiency.

Description

technical field

[0001] The invention relates to a preparation method, in particular to a preparation method of a titanium dioxide double-layer film electrode. Background technique

[0002] Batteries have been widely used in many occasions and products, and the efficiency of batteries has always been the goal that people want to improve. People have made efforts from various aspects in order to improve the efficiency of batteries, such as from new materials, new preparation methods, etc. Some people have used titanium dioxide thin films to apply them in batteries. However, the current density of titanium dioxide thin film electrodes is not enough, which affects battery efficiency. Contents of the invention

[0003] The technical problem mainly solved by the invention is that the density of the current titanium dioxide thin film electrode is insufficient, thereby affecting the battery efficiency.

[0004] In order to solve the above technical problems, the embodiment of the...
