Description

Porous carbon material manufacturing method

The present invention relates to a porous carbon material, and more particularly to a method for producing a porous carbon material.

A supercapacitor, also known as an electrochemical capacitor, is an emerging energy storage component between a conventional capacitor and a battery. Because of its light weight, miniaturization, high power density, long cycle life (>200,000 times), fast charge and discharge speed, and wide operating temperature range, supercapacitors are used in vehicle transportation, energy supply, mobile communications, and defense military. There is considerable market potential in the fields of medical equipment and consumer electronics.

The structure of the supercapacitor is that the electrodes at both ends are immersed in the electrolyte, and the separator is sandwiched between the layers. When a voltage is applied between the electrodes, the charge on the surface of the electrode will attract the opposite ions in the surrounding electrolyte solution, and these ions will adhere to the surface of the electrode to form an electric double layer to form an electric double layer capacitor. Since the distance between the two charge layers is very small (generally below 0.5 nm), a special electrode structure is used, resulting in a large capacitance.

Electrode material is one of the decisive factors affecting the capacity of supercapacitors. Ideal electrode materials require high crystallinity, good electrical conductivity, large specific surface area and micropores concentrated in a certain range (greater than 2 nm). The current electrode materials mainly include a transition metal oxide series and an activated carbon series. Although the use of a transition metal oxide as an electrode can increase the capacity of a supercapacitor, it is difficult to be commercially used in large quantities because of the high cost.

Chromatogr. 352, 3-25 proposes the use of silica gel as a solid template, will The precursor (monomer or oligomer) of the high molecular polymer is sufficiently mixed with the polymerization reaction to form a continuous network structure surrounding the silica particle, and then the high molecular polymer is carbonized.

Carbon electrode materials with good pore properties will effectively improve the overall performance of supercapacitors. However, as for the Republic of China No. I274453, such a carbon electrode material manufacturing technique has disadvantages in that it requires a long manufacturing time (about 3-7 days) and a high energy (treatment temperature of 2000 °C). In addition, in the preparation of the medium-hole carbon material, the yttrium oxide hole material is used as the secondary stencil, and after the carbonization, the cerium oxide must be removed by hydrofluoric acid to obtain the medium-hole carbon material. However, the risk of using hydrofluoric acid is extremely high, and the waste hydrofluoric acid needs to be specially treated before it can be recovered, and the cost derived therefrom is also high.

Thereafter, the mesoscale material is formed by immobilizing the shape of the organic template precursor solution by an oxide condensation reaction, and the mesoscale material is carbonized under a nitrogen atmosphere. Next, the oxide is removed by a strong acid, a strong base, a strong acid/strong alkali mixture or a trace amount of hydrofluoric acid/sodium hydroxide mixture to obtain a porous carbon material.
