Carbon Electrodes: Light And Heavy And Water-soluble

The carbon electrode material is composed of polarization resistance, an insulating layer, a hydrophobic layer, a solution layer, etc., and the carbon electrode material is made by dissolving the raw material with zero resistance (carbon element and its copolymer) in water, which should be determined according to the content of the polymer compound The gram weight of the carbon electrode material (that is, the amount of material exchange between the aqueous solution and the carbon electrode material). General electrochemical electrode material gram weight = molecular molar mass × 500c + solution potential difference × chloride ion concentration × 900h. According to research, when the temperature is high, the concentration of the solution with a larger molecular molar mass is low, and the concentration of the solution with a smaller molecular molar mass is high.

Therefore, the preparation equipment of lithium battery electrodes chooses to dissolve several kilograms of high molecular polymers (or a certain amount of ethylene glycol) in the aqueous solution dedicated to lithium battery electrodes, and then store them in a vacuum state or evaporate them to simulate the changing conditions of the cathode. It can greatly improve the purity of prepared electrode materials and reduce energy density. The low-temperature dehydration and decarburization process is consistent with the principle of lithium battery electrodes.

It's not that I don't understand polymer electrodes. However, according to dehydration in a certain way, it is possible to prepare polymer electrodes directly according to the required size, just like the use of thermal insulation film. However, this kind of polymer electrode is only a polymer base on the surface, and the gas phase and liquid phase components will contain a much smaller proportion of catalysts and other additives. So the production process cost is not low.  ps: A sketch can give you a lot of inspiration.

It is impossible to have a combination of conductivity and hydrophobicity. The dissolved carbon electrode solution you see is a very pure aqueous solution, and it has been dehydrated many times (the production of this combined solution is generally pure water, without electrolytes. Explain). In the electrode, the two factors of conductivity and hydrophobicity determine the performance of the electrode material.
