The preparation method of 9-micron aluminum is similar to the ordinary micro-preparation method. It is usually prepared by electrochemical decomposition method or chemical decomposition method. The preparation of 9-micron aluminum is relatively complex and it is important to strictly control the process parameters and reaction conditions to obtain the current characteristics. Microporous structure with pore size, porosity and uniformity. Among them, the preparation cost of the electrochemical etching method is higher and the process accuracy is greater, but the surface of the prepared product is smoother and the pore size distribution is uniform: the preparation cost of the chemical etching method is relatively Lower, but black controls the process parameters during the preparation process to ensure uniformity of product pore size and distribution.
1. High specific surface area
The surface of the 9-micron microporous aluminum junction has a pore structure, and its specific surface area is much larger than that of ordinary aluminum boxes. It can enhance the microstructure of the aluminum surface, make it easier to diffuse substances and enhance the adsorption of electrolytes, which is beneficial to improving the efficiency of electrochemical reactions.
2. High ventilation
The 9-micron microporous aluminum foil has high air permeability. The communication between the pores is conducive to the diffusion and dissipation of gas. It also has good battery explosion-proof properties.
3. Good electrical conductivity
Aluminum itself has good conductivity, and the surface of the aluminum foil treated with micropores forms microscopic electrodes and conductive channels, making it easier for electrons to transmit inside the battery.
4.Higher mechanical properties
9 micron microporous aluminum foil has good mechanical properties, can withstand greater pressure and is not easily deformed or broken.
5. Adjustable aperture, hole, porosity
The diameter and focus of the 9-meter diffuse-hole aluminum junction can be adjusted according to the process parameters during the bar making process to meet the electrical energy requirements. In addition, this type also provides a wide range of application fields, such as There is broad market development space for quasi-clean material biosensors and Tibetan electrical appliances.
